Item 8.01. Other Events

         On June 29, 2006, Equinix, Inc. ("Equinix") announced that it received
a grand jury subpoena from the U.S. Attorney for the Northern District of
California and that it intends to cooperate fully with the U.S. Attorney's
Office in connection with this subpoena. The subpoena requests documents
relating to Equinix's stock option grants and practices.

         Equinix also reported that it has been notified that a shareholder
derivative complaint was filed in the Superior Court of the State of California,
County of San Mateo on June 29, 2006. The complaint against certain current and
former officers and directors alleges that since 2000 stock option grants to
certain employees were awarded with exercise prices that were lower than the
market price on the actual grant dates and resulted in breaches of fiduciary
duties with respect to Equinix's historic stock option granting practices.
Equinix may be subject to other lawsuits from private plaintiffs concerning this
subject area, and Equinix does not currently expect to file further current
reports on Form 8-K describing such additional lawsuits.

         The full text of Equinix's press release is filed as Exhibit 99.1 to
this Report and is incorporated herein by reference.
