Item 7.01 Regulation FD Disclosure.

Item 8.01 Other Events.

As previously disclosed in the Registration Statement on Form S-4 that Equinix filed on November 25, 2009, both Equinix and Switch & Data Facilities Company, Inc. (“Switch and Data”) filed Notification and Report Forms with the Antitrust Division of the Department of Justice, or the Antitrust Division, and the Federal Trade Commission pursuant to the Hart-Scott-Rodino Antitrust Improvement Act of 1976, or the HSR Act, on November 4, 2009. As a result, the waiting period under the HSR Act with respect to the merger between Equinix and Switch and Data was scheduled to expire on December 4, 2009. However, following the submission of materials relating to the transaction to the Antitrust Division staff and consultation with the staff, Equinix intends to voluntarily withdraw its Notification and Report Form on December 3, 2009 and re-file the form on December 7, 2009. Equinix’s re-filing will give the Antitrust Division staff more time to review the information submitted by the parties and to complete its initial investigation before the staff must determine whether to issue a formal request for additional information. The effect of this re-filing will be to extend the waiting period under the HSR Act an additional 30 days to January 6, 2010.
