EQUINIX COMPLETES ACQUISITION OF EUROPEAN DATA CENTER PROVIDER IXEUROPE

Foster City, CA — September 14, 2007 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, today announced that it has completed the acquisition of IXEurope plc (“IXEurope”, AIM: IXE) originally announced by the company in June. The acquisition, which was approved by IXEurope’s shareholders and UK courts, gives Equinix a strong presence in Europe and strengthens its position as the largest provider of global network-neutral colocation and network exchange services.

IXEurope is a leader in the European network-neutral colocation market. It operates 14 data centers comprising approximately 325,000 square feet of net sellable space throughout Europe, including centers in Dusseldorf, Frankfurt, Geneva, London, Munich, Paris and Zurich. The company’s more than 450 enterprise and Internet customers include Capgemini, Citigroup and Deutsche Boerse Systems.

“The acquisition of IXEurope allows us to provide customers with a colocation solution globally and solidifies Equinix’s position as the worldwide market leader in network-neutral colocation services,” said Steve Smith, CEO of Equinix. “Our entry into the European market is strategic to our worldwide expansion efforts, as the market demand for premium data center colocation and network-neutral exchange services continues to accelerate.”

Beginning today, Equinix will integrate IXEurope’s network-neutral data center business and operations under the Equinix brand. The current IXEurope management team, including Guy Willner, IXEurope CEO, and Christophe de Buchet, IXEurope COO, will join Equinix and continue to operate the European business from the IXEurope London headquarters, which will now serve as Equinix’s European regional headquarters.

Under the terms of the acquisition, IXEurope shareholders will receive 140 British pence in cash for each IXEurope share, payable on September 28, 2007, valuing the share capital of IXEurope, on a fully diluted basis, at approximately £270.1 million or approximately $550 million plus the assumption of debt (based on exchange rates on September 13, 2007).
