    FOSTER CITY, Calif.--(BUSINESS WIRE)--June 12, 2006--Equinix, Inc.
(Nasdaq:EQIX) today announced the Company has initiated an independent
review by the audit committee of the Board of Directors to review the
Company's historical stock option practices and related accounting.
The Company requested the internal review following the release of a
third party report regarding the timing and pricing of stock option
grants at a large number of public companies. Independent counsel and
advisors are assisting the audit committee with this review.
    The Company also announced that subsequent to the initiation of
this review, it received an informal inquiry from the Securities and
Exchange Commission relating to stock option grants and practices. The

an indication by the SEC or its staff that any violation of law has
occurred, or as an adverse reflection upon any person, entity or
security. The Company intends to cooperate fully with the SEC.
