Item 1.01.

Entry into a Material Definitive Agreement.

As previously disclosed, on March 20, 2010, Switch & Data Facilities Company, Inc. (“Switch and Data”), Equinix, Inc. (“Equinix”) and Sundance Acquisition Corporation, a wholly-owned subsidiary of Equinix, amended the Merger Agreement among them dated October 21, 2009 (the “Merger Agreement”) to extend the date on which either Equinix or Switch and Data may terminate the Merger Agreement from March 21, 2010 to April 21, 2010.

On April 20, 2010, Equinix waived compliance with the condition set forth in Section 9.02(e) of the Merger Agreement as it relates to consents regarding assignment and change in control provisions in certain of Switch and Data’s leases. As a result, at this time, all conditions to the merger have been satisfied other than the expiration or termination of the waiting period imposed by the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, and conditions that by their nature can be satisfied only at the time of closing. Completion of the merger remains subject to the satisfaction or waiver of these conditions and the other closing conditions specified in the Merger Agreement as of the closing date. Subject to satisfaction of these conditions, it is expected that Switch and Data will announce the expected closing date of the merger by issuing a press release and filing that press release on Form 8-K with the Securities and Exchange Commission no later than five business days before the expected closing date.
