Networking Experts to Present Innovative Strategies at Equinix Forum for Content Providers and E-Commerce Companies

New York, NY — April 4, 2005 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, today announced that it will host a forum for enterprises, content providers and e-commerce companies that provides innovative technical strategies for enabling these companies to increase network performance and reliability, and to reduce overall networking costs.

The Equinix forum, "Building a Better Network: Improving Customer Online Experience While Reducing Costs," will feature interactive educational sessions from industry experts on methodologies for building network architectures by implementing multi-network connectivity. The forum will address how gaining network independence can improve uptime, security, DDoS mitigation and performance.

The forum is the next event in an ongoing series of forums developed by Equinix that have included the "Gigabit Peering Forum" and "Multihoming Seminar" events. Previous Equinix events have drawn hundreds of participants from leading network service providers and content companies such as Google, Qwest, SBC, Verio and Yahoo!

Featured companies scheduled to speak at the New York Content Forum include Yahoo!, America Online, The Burton Group, Prolexic Technologies and New York City Connect. Jay Adelson, founder and CTO of Equinix, will lead the forum. For a more detailed agenda and speaker information, please visit: http://www.equinix.com/e-invite/NYC04212005.htm.

Content and e-commerce companies have traditionally paid for connectivity to reach their end users. Through a variety of Equinix's interconnection services, these companies can directly reach their end-users while eliminating network costs and improving performance.

Similarly, as the costs for unexpected network downtime continue to grow for enterprises, content providers and e-commerce companies, many of these companies are establishing relationships with multiple network service providers, or "multihoming," to ensure the redundancy needed in the event of a failure to a primary provider. In addition to the operational redundancy and business continuity benefits, multihoming also increases overall IP performance.

The Building a Better Network Forum will take place on Thursday, April 21st, 2005 in New York City at the Hotel Gansevoort beginning with breakfast at 8:30 a.m. Interested parties must register by April 14th by emailing etroyer@equinix.com.
