Equinix Opens $82 Million Expansion of New York Area Data Center with ACTIV Financial and Direct Edge as Initial Customers

Second Phase of the Company's NY4 IBX Center is Currently 50 Percent Reserved by Customers, Driven by the Continued Strong Demand for Data Center Services from Financial Services Customers

SECAUCUS, NJ - May 5, 2009 - Equinix, Inc. (Nasdaq: EQIX), a provider of global data center services, today announced the opening of the second phase expansion of its New York-4 (NY4) International Business Exchange (IBX®) data center in Secaucus, NJ. ACTIV Financial, a leading provider of market data content and technologies, and next-generation displayed markets provider Direct Edge will be among the initial customers of the $82 million expansion, which will add 1,100 cabinets of capacity to Equinix's data center footprint. The expansion space is currently 50 percent booked or reserved by customers, due to strong demand for data center services in the New York area. The company is evaluating customer demand for the third and final phase expansion of the NY4 center, which is currently in the design phase.

The NY4 center is Equinix's fourth New York area IBX center. The $95 million first phase of the center was opened in November 2007 and is now nearly fully booked, with strong traction from the financial services industry in the region. At full build-out, the NY4 center will be Equinix's largest in the U.S. to date at 340,000 square feet - the size of five football fields - with an annual revenue capacity of between $95 million and $110 million. It is directly linked to the three other New York area IBX centers through redundant dark fiber links managed by Equinix.

“The opening of this new phase of the NY4 center is representative of our commitment to ongoing and measured expansion to meet the needs of our customers,” said Steve Smith, president and CEO of Equinix. “In the New York area, we continue to see strong customer demand, especially from the financial services market, even in the face of a challenging economy.”

In the New York area, many of Equinix's financial services customers participate on the Equinix Financial eXchange, a community of financial market participants that locate mission-critical infrastructure within Equinix data centers to benefit from a high-performance, low latency connectivity within a network-neutral environment. At Equinix, these companies can directly exchange data within the same physical location with strategic partners, customers and vendors, thereby optimizing their electronic trading operations. They also have access to a broad range of data center services and high-performance network connectivity providers.
