                                    PART II


               Information Required in the Registration Statement

Item 3  Incorporation of Documents by Reference

     Equinix Inc. (the "Registrant") hereby incorporates by reference into this
Registration Statement the following documents previously filed with the
Securities and Exchange Commission (the "SEC"):

     (a)  The Registrant's Annual Report on Form 10-K filed with the SEC for the
          fiscal year ended December 31, 2000; and

     (b)  The description of the Registrant's outstanding Common Stock contained
          in the Registrant's Registration Statement No. 000-31293 on Form 8-A
          filed with the SEC on August 9, 2000, pursuant to Section 12 of the
          Securities Act of 1934, as amended (the "1934 Act"), including any
          amendment or report filed for the purpose of updating such
          description.

     All reports and definitive proxy or information statements filed pursuant
to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act after the date of this
Registration Statement and prior to the filing of a post-effective amendment
which indicates that all securities offered hereby have been sold or which
deregisters all securities then remaining unsold shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents.

Item 4.  Description of Securities
         -------------------------
         Not Applicable.

Item 5.  Interests of Named Experts and Counsel
         --------------------------------------
         Not Applicable.

Item 6.  Indemnification of Directors and Officers
         -----------------------------------------

     Section 145 of the Delaware General Corporation Law authorizes a court to
award or a corporation's Board of Directors to grant indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the 1933 Act.  The
Registrant's Bylaws provide for mandatory indemnification of its directors and
permissible indemnification of officers, employees and other agents to the
maximum extent permitted by the Delaware General Corporation Law.  The
Registrant's Certificate of Incorporation provides that, pursuant to Delaware
law, its directors shall not be liable for monetary damages for breach of their
fiduciary duty as directors to the Registrant and its stockholders.  This
provision in the Certificate of Incorporation does not eliminate the fiduciary
duty of the directors, and, in appropriate circumstances, equitable remedies
such as injunctive or other forms of non-monetary relief will remain available
under Delaware law.  In addition, each director will continue to be subject to
liability for breach of the director's duty of loyalty to the Registrant for
acts or omissions not in good faith or involving intentional misconduct, for
knowing violations of law, for actions leading to improper personal benefit to
the director and for payment of dividends or approval of stock repurchases or
redemptions that are unlawful under Delaware law.  The provision also does not
affect a director's responsibilities under any other law, such as the federal
securities laws or state or federal environmental laws.  The Registrant has
entered into Indemnification Agreements with its directors.  The Indemnification
Agreements provide the Registrant's directors with further indemnification to
the maximum extent permitted by the Delaware General Corporation Law.

                Registration Statement.


Item 9. Undertakings
        ------------

        A.  The undersigned Registrant hereby undertakes: (1) to file, during
any period in which offers or sales are being made, a post-effective amendment
to this Registration Statement (i) to include any prospectus required by Section
10(a)(3) of the 1933 Act, (ii) to reflect in the prospectus any facts or events
arising after the effective date of this Registration Statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
Registration Statement and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) shall
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed with or
furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d)
of the 1934 Act that are incorporated by reference in this Registration
Statement; (2) that for the purpose of determining any liability under the 1933
Act each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof and (3) to remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the Registrant's 2000 Equity Incentive Plan, 2000 Director Option
Plan, and Employee Stock Purchase Plan.

        B.  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the 1933 Act, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is
incorporated by reference in this Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

        C.  Insofar as indemnification for liabilities arising under the 1933
Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnification provisions summarized in Item 6 or
otherwise, the Registrant has been advised that, in the opinion of the SEC, such
indemnification is against public policy as expressed in the 1933 Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

amended, the Registrant certifies that it has reasonable grounds to believe that

Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Mountain View, State of California on this 30th
day of March, 2001.
