Equinix Unveils Plan to Build its Third IBX Data Center in Sydney

The New $65 Million Investment Will Add 1,000 Cabinet Equivalents

FOSTER CITY, CA AND SYDNEY, AUSTRALIA — June 28, 2010 — Equinix, Inc. (Nasdaq: EQIX), a provider of global data center services, today announced plans to build its third International Business Exchange™ (IBX) in Sydney, Australia. The new IBX data center, called SY3, will significantly increase the company's Sydney capacity to meet the high demand for premium colocation and interconnection data center services in the Sydney market. The $65 million first phase of the SY3 IBX data center will add 1,000 cabinets and is targeted for opening during the second quarter of 2011.

“With strong demand for secure and well-connected data center space, our investment in the SY3 IBX data center highlights our ongoing commitment to delivering cutting edge facilities and data center services to support the Australian market,” said Darren Mann, managing director, Equinix Australia. “Our second Sydney IBX data center (SY2), which officially opened in early 2009, has filled ahead of our expectations. We are confident that this new capacity offering will also result in similar strong demand from both local and multinational corporate, government and financial services entities that leverage the Sydney metropolitan area as a key location for business.”

Located south of Sydney, the new IBX data center will have a total capacity for more than 3,000 cabinet equivalents when all of the phases are fully built out. The new IBX will support a standard power density of 4kVA per cabinet and capability to support much higher densities where required. The new site will have direct fiber connectivity to Equinix's SY1 and SY2 IBX data center campus, which is located less than one mile away. Interconnected by Equinix's IBXLink service, customers can enjoy a wide range of connectivity options and immediate access to over 50 network providers at the existing facilities in Sydney.
