                      2002 Annual Meeting Of Stockholders
                          To Be Held On May 15, 2002

   This Proxy Statement is furnished in connection with the solicitation of
proxies by the Board of Directors of StorageNetworks, Inc. for use at the 2002
Annual Meeting of Stockholders (the "Annual Meeting") to be held on May 15,
2002 at 10:00 a.m., Eastern Standard Time, at the Westin Hotel, 70 Third
Avenue, Waltham, Massachusetts 02451 and at any adjournment or postponements of
the Annual Meeting.

   All proxies will be voted in accordance with the stockholders' instructions
contained therein, and if no choice is specified, the proxies will be voted in
favor of the matters set forth in the accompanying Notice of Annual Meeting.
Any proxy may be revoked by a stockholder at any time before it is exercised by
delivery of written revocation to the Secretary of StorageNetworks or by voting
in person at the Annual Meeting. Attendance at the Annual Meeting will not
itself be deemed to revoke a proxy unless the stockholder gives affirmative
notice at the Annual Meeting that the stockholder intends to revoke the proxy
and vote in person.

Voting Securities and Votes Required

   On March 22, 2002, the record date for the determination of stockholders
entitled to notice of and to vote at the Annual Meeting, there were outstanding
and entitled to vote an aggregate of 98,269,414 shares of our common stock,
$.01 par value per share. Each share is entitled to one vote.

   Under our by-laws, the holders of a majority of the shares of common stock
issued, outstanding and entitled to vote on any matter shall constitute a
quorum with respect to that matter at the Annual Meeting. Shares of common
stock present in person or represented by proxy (including shares which abstain
or do not vote with respect to one or more of the matters presented for
stockholder approval) will be counted for purposes of determining whether a
quorum is present.

   The affirmative vote of the holders of a plurality of the shares of common
stock voting on the matter is required for the election of a director. The
affirmative vote of the holders of a majority of the shares of common stock
voting on the matter is required for the ratification of the selection of Ernst
& Young LLP as our independent auditors for the fiscal year ending December 31,
2002 and the approval of each of the other matters, if any, to be voted upon.

   Shares which abstain from voting as to a particular matter and shares held
in "street name" by brokers or nominees who indicate on their proxies that they
do not have discretionary authority to vote such shares as to a particular
matter, will not be counted as votes in favor of such matter and will also not
be counted as votes cast or shares voting on such matter. Accordingly,
abstentions and "broker non-votes" will have no effect on the voting of each
matter that requires the affirmative vote of a certain percentage of the votes
cast or shares voting on a matter.

   Our Annual Report for the year ended December 31, 2001 is being mailed to
stockholders with this Notice of Annual Meeting and this Proxy Statement on or
about April 8, 2002.

   A copy of our Annual Report on Form 10-K for the year ended December 31,
2001, as filed with the Securities and Exchange Commission (the "Commission"),
except for exhibits, will be furnished without charge to any stockholder upon
written request to Erica Smith, StorageNetworks, Inc., 225 Wyman Street,
Waltham, Massachusetts 02451. Exhibits will be provided upon request and
payment of an appropriate processing fee.

the Class II director.

Board and Committee Meetings

   The board of directors held nine meetings during the year ended December 31,

The board of directors has no standing nominating committee.

   The Audit Committee consists of our three outside directors, Messrs. Davoli,

Committee reviews the professional services provided by our independent
auditors, the independence of such auditors from our management, our annual
financial statements and our system of internal accounting controls. The Audit
Committee also reviews such other matters with respect to our accounting,
auditing and financial reporting practices and procedures as it may find
appropriate or may be brought to its attention. For additional information
concerning the Audit Committee, see "Report of the Audit Committee of the Board
of Directors."

non-employee director automatically received a fully-vested option to purchase
10,000 shares of common stock at an exercise price of $19.99 per share under
our 2000 Non-Employee Director Option Plan. Shares issuable upon exercise of
such options are subject to a repurchase right for two years from the date of
grant.

   We may, in our discretion, grant stock options and other equity awards to
our non-employee directors from time to time pursuant to our 2000 Stock Plan.
In addition, under our 2000 Non-Employee Director Option Plan, each new
non-employee director will be granted an option to purchase 25,000 shares of
common stock on the date he or she is first elected to the board and all
non-employee directors will be automatically granted an option to purchase
10,000 shares of common stock immediately following each annual meeting of
stockholders. Shares issued upon exercise of such options shall be subject to a
repurchase right for the applicable vesting period.

(1) All options were granted at the fair market value of our common stock as
    determined by our board of directors on the date of grant. The options vest
    over four years, subject to acceleration in certain

                                      7



   circumstances, including certain circumstances involving an acquisition,
   merger or change of control of StorageNetworks.
(2) The potential realizable value is calculated based on the term of the stock
    option at the time of grant. Stock price appreciation of 5% and 10% is
    assumed pursuant to rules promulgated by the Securities and Exchange
    Commission and does not represent our prediction of our future stock price
    performance. The potential realizable values at 5% and 10% appreciation are
    calculated by assuming that the exercise price on the date of grant
    appreciates at the indicated rate for the entire term of the stock option
    and that the stock option is exercised at the exercise price and sold on
    the last day of its term at the appreciated price.
(3) These options were cancelled following the termination of Mr. Fehrnstrom's
    employment in November 2001.

Section 16(a) Beneficial Ownership Reporting Compliance

   Based solely on our review of copies of reports filed by all of our
executive officers and directors who are required to file reports, referred to
as reporting persons, pursuant to Section 16(a) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), or inquiries made to certain
reporting persons, we believe that during 2001 all filings required to be made
by the reporting persons were timely made in accordance with the requirements
of the Exchange Act, other than the following: the sale of 50,000 shares of our
common stock in two transactions by Mr. Clavin which were reported on a late
Form 4 filing; one late Form 4 filing by Mr. Davoli relating to a pro rata
distribution to him of 711 shares of our common stock from a limited
partnership; and one late Form 4 filing by William Schleyer, a former director,
relating to a pro rata distribution to him of 43,988 shares of our common stock
from a limited liability corporation.

Compensation Committee Report on Executive Compensation

   The Compensation Committee of our board of directors has furnished the
following report on executive compensation.

                                      8



   The Compensation Committee of StorageNetworks' board of directors, which
consists of Messrs. Davoli, Gaal and Lambert, reviews executive salaries,
administers StorageNetworks' stock plans and any executive bonus and other
executive incentive plans and approves the salaries and other benefits of its
executive officers. In addition, the Compensation Committee consults with
StorageNetworks regarding its benefit plans and is responsible for reviewing
StorageNetworks' overall compensation policies and practices.

  Compensation Philosophy

   Since StorageNetworks' inception in October 1998, StorageNetworks has sought
to attract, retain and reward executive officers primarily through long-term
equity incentives in the form of stock options. As such, the salary component
of the executive officers' compensation reflected base salary at a lower level
and the stock component at a higher level than that of more established
companies in similar industries. In 2001, compensation for StorageNetworks'
executive officers consisted of base salary and potential bonuses based upon
the executive officer's individual performance and the overall performance of
StorageNetworks. The executive compensation philosophy is that a significant
portion of executive compensation should be tied directly to the performance of
StorageNetworks as a whole. By linking compensation to StorageNetworks'
business objectives, StorageNetworks believes that a performance-oriented
environment is created for its executives and other employees.

   StorageNetworks' executive compensation program for 2001 was also intended
to align executive and stockholder interests by providing executives with an
equity interest in StorageNetworks through the granting of stock options. In
general, the size of option grants were recommended by Peter Bell, Chairman of
the Board, Chief Executive Officer and President, to the full board or the
Compensation Committee for approval. These recommendations were reviewed on the
basis of various factors, including the executive's responsibilities, the
executive's past, present and expected contributions to StorageNetworks and
current market grants in companies of similar size, market capitalization and
industry. The option grant to Mr. Bell during 2001 was determined solely by the
Compensation Committee.

  Compensation in 2001

   Base Salary.  Base salaries for fiscal 2001 were, and executive compensation
for the upcoming fiscal year will be (except for Mr. Bell and Mr. Miller), set
within the range of compensation of executive officers that have comparable
qualifications, experience and responsibilities at companies in similar
businesses of comparable size and success. The Committee intends to continue to
adjust compensation appropriately in order to compete for and retain executives
who operate StorageNetworks effectively and to align the interests of its
executive officers with the long-term interests of stockholders.

   Incentive Bonus.  During 2001, the Company's bonus plan was based upon
StorageNetworks' overall performance and upon individual performance against
individual objectives during the year. In general, fifty percent of an
individual's bonus was based on the achievement of individual performance goals
and fifty percent was based on StorageNetworks' overall performance. For 2002,
executive officers will also be eligible to receive a portion of their annual
cash compensation based upon the performance of StorageNetworks, as well as
individual performance. The Committee intends to approve an executive bonus
plan each year.

   Long-Term Incentives.  StorageNetworks strongly believes in granting stock
options to its executive officers to tie executive officer compensation
directly to the long-term success of StorageNetworks and increases in
stockholder value. In determining the size of each stock option grant awarded
to executive officers in the future, the executive officer's position with
StorageNetworks, the executive officer's past performance and the number and
price of unvested options then held by the executive officer will be taken into
account. Stock options granted to executive officers have an exercise price
equal to the fair market value on the date of grant and vest over a four-year
period. Vesting of the options of certain executive officers may be accelerated
upon a change in control of StorageNetworks and in other limited circumstances.
For additional information concerning such accelerated vesting, see "Certain
Relationships and Related Party Transactions--Agreements with Executive
Officers and Change of Control Provisions."

  Chairman and Chief Executive Officer Compensation

   Mr. Bell has served as StorageNetworks' Chief Executive Officer and
President since October 1998 and as its Chairman of the Board since January
2000. The Compensation Committee determines Mr. Bell's salary based on
comparative salaries of chief executive officers of similar companies in
similar industries and the overall performance of StorageNetworks. In 2000, Mr.
Bell received a salary of $179,167 and a bonus of $100,000. During 2001, Mr.
Bell received a salary of $225,000, a bonus of $100,000, and an option to
purchase 250,000 shares of common stock, based primarily upon the significant
accomplishments of StorageNetworks during 2000 and 2001, including its
successful transition to a public company, its revenue growth, and its
achievement of certain profitability metrics. Effective as of February 2002,
Mr. Bell and Mr. Miller, StorageNetworks' founders, have elected to forego
their base salary for the remainder of the year. Accordingly, they will receive
no further salary during 2002.

  Policy on Deductibility of Executive Compensation

   Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"), disallows a deduction to public companies for compensation over
$1,000,000 paid to the company's chief executive officer and four most highly
compensated executive officers. Qualifying performance-based compensation will
not be subject to the deduction limit if certain requirements are met. Having
considered the requirements of Section 162(m) of the Code, the Compensation
Committee believes that grants made pursuant to StorageNetworks' Amended and
Restated 1998 Stock Incentive Plan and 2000 Stock Plan meet such requirements
and are, therefore, exempt from the limitations on deductibility. Historically,
the compensation of each executive officer has been well below the $1,000,000
limit. The Compensation Committee's present intention is to structure its stock
option grants and certain other equity-based awards in a manner that complies
with Section 162(m) of the Code unless the Compensation Committee believes that
such compliance would not be in the best interest of StorageNetworks or its
stockholders.

                                          By the Compensation Committee of the
                                          Board of Directors

                                          Robert A. Davoli
                                          Stephen J. Gaal
                                          Michael A. Lambert

Compensation Committee Interlocks and Insider Participation

   The current members of the Compensation Committee are Messrs. Davoli, Gaal
and Lambert, each of whom served on the Compensation Committee during 2001. No
member of the Compensation Committee was at any time during 2001, or formerly,
an officer or employee of StorageNetworks or any of our subsidiaries, and no
member of the Compensation Committee had any relationship with StorageNetworks
requiring disclosure under Item 404 of Regulation S-K under the Exchange Act.

   None of our executive officers has served as a director or member of the
compensation committee (or other committee serving an equivalent function) of
any other entity, one of whose executive officers served as a director of or
member of the Compensation Committee.

Report of the Audit Committee of the Board of Directors

   The Audit Committee of StorageNetworks' Board of Directors is composed of
three members and acts under a written charter first adopted and approved in
March 2000. The members of the Audit Committee are independent directors, as
defined by its charter and the rules of the Nasdaq National Market. The Audit
Committee held six meetings during the fiscal year ended December 31, 2001.

                                      10



   The Audit Committee reviewed StorageNetworks' audited financial statements
for the fiscal year ended December 31, 2001 and discussed these financial
statements with StorageNetworks' management. Management is responsible for
StorageNetworks' financial reporting process, including its system of internal
controls, and for the preparation of consolidated financial statements in
accordance with generally accepted accounting principles. StorageNetworks'
independent auditors, Ernst & Young LLP, are responsible for performing an
independent audit of, and issuing a report on, those financial statements. The
Audit Committee is responsible for monitoring and overseeing these processes.
The Audit Committee's oversight does not provide an independent basis to
determine that management has maintained appropriate accounting and financial
reporting principles or policies, or appropriate internal controls and
procedures designed to assure compliance with accounting standards and
applicable laws and regulations.

   As appropriate, the Audit Committee reviews and evaluates, and discusses
with StorageNetworks' management, internal accounting, financial and auditing
personnel and the independent auditors, the following:

    .  the plan for, and the independent auditors' report on, each audit of
       StorageNetworks' financial statements;

    .  StorageNetworks' financial disclosure documents;

    .  management's selection, application and disclosure of critical
       accounting policies;

    .  StorageNetworks' accounting practices, principles, controls or
       methodologies;

    .  significant developments or changes in accounting rules applicable to
       StorageNetworks; and

    .  the adequacy of StorageNetworks' internal controls and accounting,
       financial and auditing personnel.

   Management represented to the Audit Committee that StorageNetworks'
financial statements had been prepared in accordance with generally accepted
accounting principles.

   The Audit Committee also reviewed and discussed the audited financial
statements and the matters required by Statement on Auditing Standards No. 61
(Communication with Audit Committees) with Ernst & Young LLP. SAS 61 requires
StorageNetworks' independent auditors to discuss with the Audit Committee,
among other things, the following:

    .  methods to account for significant unusual transactions;

    .  the effect of significant accounting policies in controversial or
       emerging areas for which there is a lack of authoritative guidance or
       consensus;

    .  the process used by management in formulating particularly sensitive
       accounting estimates and the basis for the auditors' conclusions
       regarding the reasonableness of those estimates; and

    .  disagreements with management over the application of accounting
       principles, the basis for management's accounting estimates and the
       disclosures in the financial statements.

   The Company's independent auditors also provided the Audit Committee with
the written disclosures and the letter required by Independence Standards Board
Standard No. 1 (Independence Discussions with Audit Committees). Independence
Standards Board Standard No. 1 requires auditors annually to disclose in
writing all relationships that in the auditor's professional opinion may
reasonably be thought to bear on independence, confirm their perceived
independence and engage in a discussion of independence. In addition, the Audit
Committee discussed with the independent auditors their independence from
StorageNetworks. The Audit Committee also considered whether the independent
auditors' provision of certain other, non-audit related services to
StorageNetworks is compatible with maintaining such auditors' independence.

                                      11



   Based on its discussions with management and the independent auditors, and
its review of the representations and information provided by management and
the independent auditors, the Audit Committee recommended to the Company's
board of directors that the audited financial statements be included in the
Company's Annual Report on Form 10-K for the year ended December 31, 2001. The
Audit Committee and the board of directors have also recommended, subject to
stockholder approval, the selection of StorageNetworks' independent auditors.

Comparative Stock Performance

   The following graph compares the cumulative total return to stockholders of
our common stock for the period from June 30, 2000, the date our common stock
was first traded on the Nasdaq National Market, through December 31, 2001, with
the cumulative total return over such period of (i) the Nasdaq Stock Market
(U.S.) Index and (ii) the S&P Technology Sector Index. The graph assumes the
investment of $100 in our common stock and in each of such indices (and the
reinvestment of all dividends). The performance shown is not necessarily
indicative of future performance.

   In accordance with the rules of the Commission, cumulative total return data
for the common stock is based on the closing sale price of $90.25 per share on
June 30, 2001, rather than the initial public offering price of $27.00 per
share.

   Notwithstanding anything to the contrary set forth in any of our filings
under the Securities Act of 1933, as amended (the "Securities Act"), or the
Exchange Act, that might incorporate other filings with the Commission,

Certain Relationships and Related Party Transactions

   Stockholder Agreements.  In connection with sales of preferred convertible
and common stock, StorageNetworks entered into a stockholder rights agreement
pursuant to which holders of such preferred stock and common stock are entitled
to registration rights with respect to their preferred and common shares. Each
of our current directors is a party to the stockholder rights agreement or is
affiliated with entities that are or were party to the agreement.

  Agreements With Executive Officers and Change of Control Provisions.

   In March 1999 StorageNetworks entered into an employment agreement with Paul
C. Flanagan. The employment agreement provides for an annual base salary and
bonus compensation if certain annual targets are met. If Mr. Flanagan's
employment is terminated without cause within one year subsequent to a change
of control of the Company, he will continue to receive his base salary until
the earlier of 180 days after termination of employment or his commencement of
employment with another party. He will also receive a lump sum payment of the
portion of his expected annual bonus, prorated for the portion of the calendar
year he was employed prior to termination. In August, 2001, StorageNetworks
entered into an agreement with Mr. Flanagan whereby certain options granted to
Mr. Flanagan in 1999 for an aggregate of 700,000 shares were accelerated and
became immediately exercisable, resulting in immediate vesting of 331,250
shares.

   All of the stock options granted to Mr. Bell, Mr. Miller and Mr. Clavin, and
the remaining options granted to Mr. Flanagan, become exercisable over a
four-year period from the date of grant; but upon a merger, consolidation or
sale of substantially all of our assets, any then unvested portion of such
options becomes immediately exercisable. The unvested portions of the options
granted to Mr. Keohane become immediately exercisable if his employment is
terminated in certain circumstances within one year of a change of control
event.

   In August, 2001, we entered into contingent compensation payment agreements
with Mr. Bell, Mr. Miller and Mr. Flanagan. Under the terms of these
agreements, we will make additional payments (sometimes referred to as gross-up
payments) to these executives in the event the executive receives any
contingent compensation payments as the result of a change of ownership or
control of StorageNetworks. The additional payments will be equal to the amount
of excise tax owed by the executive upon receipt of the contingent compensation
payment plus the amount necessary to pay all additional taxes attributable to
the receipt of the additional payment.

  Other Transactions with Stockholders and Related Parties

   In June 2000, we entered into a master lease agreement under which we lease
certain equipment from Dell Financial Services L.P., an affiliate of one of our
former five percent stockholders, Dell USA L.P., and an affiliate of Dell
Computer Corporation. As of December 31, 2001, Dell USA L.P. held less than
five percent of our common stock. Mr. Lambert, one of our directors, is
employed by Dell Computer Corporation. During the year ended December 31, 2001,
we leased approximately $430,111 of equipment under this lease agreement.
During the year ended 2001, StorageNetworks purchased approximately $75,286 of
computers and related equipment from Dell Computer Corporation. In May 2000,
StorageNetworks entered into an agreement for professional services with Dell
Marketing L.P., an affiliate of Dell USA L.P., under which Dell Marketing L.P.
may engage StorageNetworks to perform professional services for it or for its
customers. During 2001, Dell Marketing L.P. paid StorageNetworks an aggregate
of $81,337 under this agreement.

                                      13



               RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

   The board of directors has selected Ernst & Young LLP, independent auditors,
to audit StorageNetworks' financial statements for the year ending December 31,
2002. Ernst & Young LLP has audited our financial statements for each fiscal
year since our inception. Although stockholder approval of the selection of
Ernst & Young LLP is not required by law, the board of directors believes that
it is advisable to give stockholders an opportunity to ratify this selection.
The affirmative vote of holders of a majority of the shares of common stock
represented at the meeting is necessary to ratify the selection of Ernst &
Young LLP as our independent auditors and the board of directors recommends
that the stockholders vote FOR ratification of such selection. In the event of
a negative vote, the board of directors will reconsider its selection.

   Representatives of Ernst & Young LLP are expected to be present at the
Annual Meeting with the opportunity to make a statement if they desire to do
so, and are expected to be available to respond to appropriate questions.

Audit Fees

   Ernst & Young LLP billed us an aggregate of $130,134 for audit-related fees
rendered in connection with the audit of our financial statements for the year
ended December 31, 2001 and the reviews of the financial statements included in
each of our Quarterly Reports on Form 10-Q during 2001.

Financial Information Systems Design and Implementation Fees

   Ernst & Young LLP did not perform any professional services in connection
with our financial information systems design or implementation, the operation
of our information system or the management of our local area network.

All Other Fees

   Ernst & Young LLP billed us an aggregate of $104,681 in fees for other
services, primarily for tax advisory fees and fees for services in connection
with SEC registration statements rendered to us and our affiliates, for the
fiscal year ended December 31, 2001.

Board Recommendation

   The board of directors believes that the selection of Ernst & Young LLP as
independent auditors for the year ending December 31, 2002 is in the best
interests of StorageNetworks and its stockholders and therefore recommends that
the stockholders vote FOR this proposal.

                                 OTHER MATTERS

   The board of directors does not know of any other matters that may come
before the meeting. However, if any other matters are properly presented to the
meeting, it is the intention of the persons named in the accompanying proxy to
vote, or otherwise act, in accordance with their judgment on such matters.

   All costs of solicitation of proxies will be borne by StorageNetworks. In
addition to solicitations by mail, StorageNetworks' directors, officers and
regular employees, without additional remuneration, may solicit proxies by
telephone, telegraph and personal interviews. Brokers, custodians and
fiduciaries will be requested to forward proxy soliciting material to the
owners of stock held in their names, and StorageNetworks will reimburse them
for their reasonable out-of-pocket expenses incurred in connection with the
distribution of proxy materials.


                                      14



Deadline for Submission of Stockholder Proposals for the 2003 Annual Meeting

   Proposals of stockholders intended to be presented at the 2003 Annual
Meeting pursuant to Rule 14a-8 promulgated under the Exchange Act, must be
received by StorageNetworks no later than December 9, 2002 in order that they
may be included in the proxy statement and form of proxy relating to that
meeting.

   In addition, StorageNetworks' by-laws require that StorageNetworks be given
advance notice of stockholder nominations for election to StorageNetworks'
board of directors and of other business that stockholders wish to present for
action at an annual meeting of stockholders (other than matters included in
StorageNetworks' proxy statement in accordance with Rule 14a-8). The required
notice must be delivered by the stockholder and received by the secretary at
the principal executive offices of StorageNetworks (a) no earlier than 90 days
before and no later than 70 days before the first anniversary of the preceding
year's annual meeting, or (b) if the date of the annual meeting is advanced by
more than 20 days or delayed by more than 70 days from the first anniversary
date, (i) no earlier than 90 days before the annual meeting and (ii) no later
than 70 days before the annual meeting or ten days after the day notice of the
annual meeting was mailed or publicly disclosed, whichever occurs first.

   THE BOARD OF DIRECTORS ENCOURAGES STOCKHOLDERS TO ATTEND THE MEETING.
WHETHER OR NOT YOU PLAN TO ATTEND, YOU ARE URGED TO COMPLETE, DATE, SIGN AND
