Equinix Expands Sydney IBX Data Centre to Accommodate Strong Regional Growth

Sydney, Australia — November 7, 2006 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, today announced an extensive U.S. $3.8 million (AUD $5 million) expansion of its Sydney Internet Business Exchange™ (IBX®) center. The expansion comes after Equinix's recently announced expansions in the U.S., continued strong demand from local and regional businesses in the Australia market, and strong financial returns for Equinix's Australia operations.

The expansion, which will increase the existing capacity of the Sydney IBX by 50% and add approximately 10,000 square feet and 400 cabinets, will enable Equinix to accommodate customers' increasing business needs for collocation and connectivity to a large aggregation of network service providers. The Sydney IBX currently has more than 150 customers, including CITEC, Hostworks Group Limited and Hermes Precisa Pty Ltd (HPA), and it facilitates a critical role in the interconnection and peering infrastructure of many enterprises, content companies, networks and systems integrators. Equinix intends to begin placing customers in the expanded space at the Sydney IBX in April of 2007. Equinix guidance provided on October 25, 2006 remains unchanged as capital expenditures for this expansion were included in that guidance.

Sydney is one of Equinix's fastest growing markets in the Asia-Pacific region, with a more than 70 percent increase in revenue from 2004 to 2005. Driving much of this growth has been Equinix's ability to provide direct access to the largest aggregation of network service providers within the same physical location. At the same time, the data centre market in Australia is undergoing significant expansion, and demand for quality collocation space is now outpacing supply. This trend is mirrored in the U.S. where Equinix has undergone significant expansion and now has multiple IBX data centers in several markets including the Silicon Valley, Washington, D.C., Los Angeles, New York and Chicago areas.

"Equinix continues to grow and we are looking at further expansion in the region through both building new data centers and forming strategic partnerships," said Doug Oates, Managing Director of Equinix Australia. "This expansion in Australia is a response to demands from corporations seeking secure and robust facilities to deploy a convenient connectivity infrastructure by working under the same roof as wide diversity of telecommunications providers.”
