Equinix, Inc. served with a lawsuit

CURRENT REPORT

Pursuant to Section 13 or 15(d) of the

Securities Exchange Act of 1934

On September 14, 2010, Equinix, Inc. was served with a lawsuit filed in the Superior Court of California in Santa Clara County by 529 Bryant Street Partners LLC (“Plaintiff”) against our wholly owned subsidiaries Switch & Data CA Nine LLC (“Tenant”) and Switch & Data Facilities Company, Inc. (“Guarantor”). The lawsuit alleges that Tenant breached certain non-monetary obligations under its lease (the “Lease”) of our data center located at 529 Bryant Street in Palo Alto, California (the “Premises”) and seeks monetary damages, specific performance of those non-monetary obligations and ejectment of Tenant from the Premises. The lawsuit also alleges that Guarantor has breached its obligations under its guaranty of the Lease. We believe that the lawsuit as a whole lacks merit and that the remedies sought are excessive. We are currently in discussions with Plaintiff to reach a mutually agreeable settlement, but intend to defend the lawsuit vigorously.
