Samsung Networks to Enhance Network Services with Move to Equinix Internet Hubs

Foster City, CA — October 11, 2005 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, today announced the addition of Samsung Networks, Inc., an information technology affiliate of the Samsung Group, into Equinix Internet Business Exchange™ (IBX®) centers in the New York and Silicon Valley areas. As a result, Samsung Networks will operate within reliable, secure and high-performance data centers that offer immediate access to every major global network, enabling Samsung to expand and upgrade its network, peer with other networks and offer its network services to the other companies operating within Equinix's hubs.

Samsung Networks connects more than 70 countries around the world through a global infrastructure that provides a comprehensive portfolio of communications services, including network, telephone, digital multimedia and the company's ®E-Biz service. Samsung will use Equinix's network- rich data center environment to directly connect with the large aggregation of leading carriers, ISPs and network service providers within the same physical location. By operating within this Internet ecosystem, Samsung will have the opportunity to directly link with these companies, rather than connecting to them in multiple, disparate locations and over long distances. This direct connectivity reduces bottlenecks in the path between origin and destination, providing improved performance levels.

To facilitate interconnection within Equinix's centers, Samsung will utilize Equinix's leading exchange services, including Equinix Exchange and Equinix Direct. Equinix Exchange facilitates ISP and content peering among Equinix customers through a central switching fabric and has become a strategic element in the increasingly important peering infrastructure of many ISPs, content companies, and content distributors. The streamlined connectivity provided by Equinix Exchange, which will begin offering a 10 Gigabit Ethernet capability later this year, enhances performance and reliability of network operations.

In Equinix's Silicon Valley IBX center, Samsung will utilize Equinix Direct, a service that enables buyers and sellers of Internet network connectivity to easily and cost effectively establish business relationships with each other. The service will provide Samsung with a one-stop solution to expand their network by directly connecting to multiple networks, avoiding costly and prohibitive usage minimums by bandwidth providers, lengthy provisioning times, installation of complex router configurations for each network service provider, and the administrative challenge of managing multiple invoices from each network service provider.

"Equinix provides an ideal infrastructure from which we can greatly enhance and expand our network, through directly interconnecting with an aggregation of strategic networks under one roof," said Mr. Hong-Kyoon Chun, chief technical officer of Samsung Networks, Inc. "Equinix is the only place where this critical mass of networks exists, and Equinix's innovative exchange services simplify the process for establishing relationships with our strategic partners and customers operating within their IBX centers."

"As a leading global network service provider with extensive routes in Korea, Samsung Networks will be a valuable addition to the lineup of networks currently operating on the Equinix Exchange platform," said Margie Backaus, chief business officer for Equinix. "Samsung compliments the extensive lineup of more than 200 networks currently available at Equinix, including all of the major global carriers, ISPs and network service providers."
