FOR IMMEDIATE RELEASE

EQUINIX INCREASES TERMS FOR ACQUISITION OF IXEUROPE;

INVESTORS AGREE TO HARD IRREVOCABLE TERMS

In Response to Potential Rival Bid, Equinix and IXEurope Reach New Agreement; Deal Expected to Close in September

Foster City, CA and London– July 18, 2007 (11:00 PM PT) – Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, and IXEurope Plc (“IXEurope”, AIM: IXE), a provider of colocation services in Europe, announced today that the boards of its subsidiary, Equinix UK Limited (Equinix UK), and IXEurope have reached agreement on improved terms for the acquisition of all of the outstanding shares of IXEurope for 140 pence per share. In exchange, Equinix UK has now received hard irrevocable undertakings from the IXEurope directors and from shareholders who together hold approximately 67 percent of the existing issued ordinary share capital of IXEurope to vote in favor of the resolutions to approve the acquisition.

“The announcement of our intention to acquire IXEurope three weeks ago created additional interest in the company and an unsolicited approach from another company,” said Steve Smith, CEO of Equinix. “The acquisition of IXEurope by Equinix will solidify Equinix’s position as the world’s market leading colocation provider with high-quality data centers across the United States, Asia-Pacific and Europe and is strategic to our growth. This announcement today secures our acquisition plan at a fair and equitable price.”

“We believe that Equinix’s offer is a good deal for IXEurope shareholders,” said Guy Willner, CEO of IXEurope. “The directors of IXEurope have unanimously agreed to recommend that IXEurope shareholders vote in favor of it.”

Equinix intends to integrate IXEurope’s network-neutral data center business and operations under the Equinix brand. IXEurope’s business includes 14 data centers comprising more than 380,000 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 Avis Europe, Citigroup, Deutsche Boerse, Merrill Lynch, Rackspace and SurfControl.

Equinix is targeting completion of the transaction in mid-September 2007. The closing and its timing are subject to the approval of IXEurope’s stockholders and the UK courts as well as satisfaction or waiver of other closing conditions. It is still intended that the acquisition be implemented by means of a scheme of arrangement, although Equinix UK still reserves the right to implement the acquisition by way of a takeover offer directly to IXEurope shareholders.

Under the terms of the revised announcement, IXEurope shareholders will receive 140 pence in cash for each IXEurope share held at the Scheme Record Time, valuing the share capital of IXEurope, on a fully diluted basis, at approximately £270.1 million or $555.0 million plus the assumption of debt. The additional $73.0 million over the original price of $482.0 million is comprised of $58.0 million for the 12.0 percent premium over the initial offer by Equinix of 125 pence per share on June 27, 2007 and $15.0 million of currency fluctuation which has been partially offset by hedging activities.
