Multiple Networks and Service Providers in Equinix's

Neutral IBX Centers Allows Portal to Enhance Speed and Reliability

Equinix, Inc. (Nasdaq:EQIX), creator and operator of neutral Internet Business Exchange(TM) (IBX(R)) centers, today announced that About.com, the Internet's most complete targeted environment for users and marketers, has selected Equinix as the Internet exchange services provider for its Web site operations. About will move to Equinix's Dallas IBX center in August 2001, with possible expansion to additional centers later.

By locating its network and site operations within an Equinix IBX center, About will access a unique aggregation of leading network and service providers with whom it can directly interconnect to optimize operational efficiency. Equinix currently has 57 network service providers participating in its neutral centers, including carriers, Internet Service Providers (ISPs) and Metropolitan Area Networks (MANs). Through direct interconnection with these and other critical Internet business partners within a single IBX center, Internet businesses such as About can avoid the cost, latency and service issues of connecting to their partners over significant geographic distances and multiple Internet "hops." Equinix's aggregation of providers also offers About the flexibility to quickly scale operations and work with multiple providers.

"Through Equinix's uniquely neutral environment, we have developed a robust hosting solution that will enhance the performance of the About network," said Chris Coluzzi, vice president operations for About.com. "The flexibility of the Equinix business model allows us to select the best technical and business solutions from a myriad of providers. Equinix will play a significant role in the growth and diversification of the About network."

With more than 700 topic sites, each overseen by a professional Guide, the About Network provides users with the Internet's best link directories, original content, community features and commerce opportunities. Media Metrix (June 2001) ranks About.com as the 7th largest Web property.

"As the seventh largest web property, the About network requires a web solution that ensures reliability and uptime, while offering the flexibility to scale and change operations," said Jay Adelson, co-founder and CTO of Equinix. "The abundant choice of leading service providers and service options in Equinix IBX centers offers an ideal environment for today's high performance web operations, such as About."

Equinix IBX centers enable enterprises and Internet businesses to quickly, easily and privately interconnect with a choice of business partners, service providers and customers, providing them with the flexibility, speed and adaptability they need to accelerate business growth and improve Internet performance.
