Equinix Continues Expansion in Sydney with Lease of Second IBX Center

Sydney, Australia — October 31, 2007 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, today announced that it is expanding its presence in the Sydney market in response to growing demand in the region for premium colocation and data center services. The new Internet Business Exchange™ (IBX®) center, located on the same campus as Equinix's first IBX in Sydney, will add approximately 2,900 square meters (31,204 sq. ft.) and 650 cabinets to Equinix's capacity in the market.

Equinix intends to invest approximately AUD $32.0 million or approximately USD $29.5 million, to build the new Sydney2 IBX. The majority of the capital expenditures will be incurred in 2008.

The new Sydney2 center will offer direct access to the more than 35 networks and 180 enterprises and content companies already operating within the Sydney1 IBX, a principal element of Equinix's value proposition. The IBX will cater to customers with high power density requirements with the ability to support 4 kW per cabinet, which is double the average power per cabinet for most data centers in Sydney. Equinix plans to begin placing customers in the new center by the beginning of fourth quarter of 2008.

As part of Equinix's efforts at environmental conservation, the new Sydney2 center will be designed with the ability to switch from chilled water cooling to natural air cooling, under specific temperature and humidity conditions. Cool air, drawn from outside the building, is cleaned and conditioned to cool the center, resulting in reduced carbon emissions and energy consumption.

"As global demand continues to outpace supply, we continue to expand locally to meet market demands for both space and power," said Doug Oates, managing director of Equinix Sydney. "The acquisition of a second IBX in Sydney enables us to continue supporting our customers with robust infrastructure, network access and various managed services so that they can focus on growing their core business.”
