        Equinix Announces Receipt of Nasdaq Deficiency Notice

    FOSTER CITY, Calif.--(BUSINESS WIRE)--Feb. 12, 2007--Equinix, Inc.
(Nasdaq:EQIX), the leading provider of network-neutral data centers
and Internet exchange services, today reported that it received a
Nasdaq Staff Deficiency Letter on Friday, February 9, 2007, indicating
that the Company no longer complies with Nasdaq's audit committee
requirements as set forth in Marketplace Rule 4350. Equinix has a cure
period until August 8, 2007 to comply with the requirements of the
Nasdaq rule.

    The letter was received following the Company's notification to
the Nasdaq Stock Market, Inc., on Thursday, February 8, 2007, of a
vacancy created by the resignation of Mr. Louis J. Lavigne, Jr., a
member of the Audit Committee of Equinix's Board of Directors (the
"Board"). Mr. Lavigne was the Audit Committee's chairman and
considered its financial expert.

    The Company is in the process of searching for a new candidate to
serve on its Board and Audit Committee who possesses qualifications
that will satisfy both the independence requirements and the audit
committee financial expert requirement.

    Mr. Lavigne joined Equinix's Board on August 11, 2005 and served
as chairman of the Audit Committee of the Board and as a member of the
Real Estate Committee of the Board. The resignation of Mr. Lavigne was
solely for personal reasons and did not involve any disagreement with
Equinix, Equinix's management or Equinix's Board of Directors.
