Equinix Opens Fifth IBX Data Center in Dallas

$25 Million Phase 1 Dallas Expansion Supports Strong Demand for Peering and Interconnection Services Among Networks and IT Services Companies

REDWOOD CITY, Calif. – April 5, 2011 Equinix, Inc. (Nasdaq: EQIX), a provider of global data center services, today announced the opening of its fifth International Business Exchange™ (IBX®) data center in Dallas, Texas.

One of 35 global markets served by Platform Equinix™, Dallas-Fort Worth is the fourth largest metro area in the United States and the twelfth largest in the world. Because of its central location in the U.S. and proximity to many telecommunications companies, Dallas is a key Internet and peering exchange point for networks.

The new Dallas IBX further extends Platform Equinix, adding approximately 34,000 gross square feet of data center space and 450 cabinet equivalents. The facility represents an investment of approximately $25 million for the first phase of a two-phase build-out. The second phase has planned capacity for approximately 23,000 gross square feet of additional space and approximately 450 additional cabinet equivalents. Interconnection services available in the new IBX include the Equinix Internet Exchange™ for public and private peering, and the Equinix Carrier Ethernet Exchange, which enables Ethernet buyers and sellers to discover, transact and interconnect to each other.

“Equinix has long catered to the high concentration of telecommunications and IT services companies in and around Dallas-Fort Worth,” said Charles Meyers, president of North America for Equinix. “With strong demand for our peering and interconnection services in this market we continue to invest in the Dallas-Fort Worth metro to support our customers’ and partners’ growth and performance requirements.”
