Equinix Opens Fourth Data Center in the Silicon Valley

Foster City, CA — August 1, 2006 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, today announced the opening of its fourth Internet Business Exchange™ (IBX®) center in the Silicon Valley. The center will provide Equinix with additional data center space to respond to strong customer demand in one of the fastest growing markets for data center colocation and Internet exchange services. The new 120,000 square foot center is located in Sunnyvale and will add approximately 1,800 cabinets and increase Equinix's Silicon Valley footprint to more than 500,000 square feet. The center was originally built-out in 2001 at an estimated cost of $80 million and was acquired by Equinix through a long-term lease announced 14 months ago. Equinix is investing $15.0 million in upgrades to bring the new center up to Equinix industry-leading standards.

The center is interconnected to Equinix's three other Silicon Valley centers through redundant dark fiber links managed by Equinix, enabling new customers in each center to have direct access to the more than 50 networks already operating in Equinix's Silicon Valley centers, as if they were in the same location. It also features a physical infrastructure that is consistent with Equinix's industry-leading standards for high-performance, security, environmental control and power availability.

With more than 200 network service providers, nine of the top ten Web properties (according to Nielsen NetRatings) and hundreds of other companies operating within its IBX centers, Equinix's neutral, network-rich IBX centers are widely recognized as the leading hubs for the exchange of core Internet traffic.

“The Silicon Valley continues to be a critical and a fast-growing junction point for enterprises, content providers and network service providers seeking to interconnect their networks and exchange data traffic with each other,” said Peter Van Camp, CEO of Equinix. “This new center provides a smooth growth path for our current customers in Silicon Valley and with this new addition to its IBX centers, Equinix continues to solidify its market leading position in the region.”
