Equinix Enhances its Financial Exchange Platform with Connectivity to Chicago Mercantile Exchange

Foster City, CA — October 3, 2006 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, today announced a joint service agreement with the Chicago Mercantile Exchange (www.CME.com), the world's largest and most diverse financial exchange, offering direct fiber connectivity between Equinix's Chicago Internet Business Exchange™ (IBX®) center and the CME. The service is available immediately to customers of the Equinix Financial eXchange™ service in the Chicago IBX and CME customers.

The agreement further strengthens the position of Equinix's Chicago IBX center as a strategic hub for the connectivity and IT operations of financial trading companies. With critical requirements for the highest levels of security and uptime, these companies can directly interconnect with an aggregation of network service providers and other trading partners within Equinix's Chicago hub, eliminating the cost as well as the performance degradation associated with linking to multiple partners over great geographic distances, while enhancing redundancy and reliability.

The new connectivity platform with CME will be offered to CME customers through Equinix Financial eXchange (FX), a service designed to meet the specific needs of the financial trading industry. FX offers a fast, reliable and convenient platform for banks, financial trading companies and financial exchanges to interconnect with each other and with multiple network service providers in order to execute financial transactions. The results are faster transaction processing, lower costs, and enhanced trading capabilities. Some of the largest names in the industry are participating in the service, including optionsXpress, Rosenthal Collins Group LLC and TradeStation.
