Equinix Signs 1000th Customer

April 27, 2005; 10:35 AM

Foster City, CA - April 27, 2005 - Equinix, Inc. (Nasdaq: EQIX), the leading
provider of network-neutral data centers and Internet exchange services,
today announced that the number of companies operating within Equinix's
Internet hubs has reached 1,000 with the addition of New York magazine to
Equinix's New York Internet Business ExchangeT (IBX®) center located in
Secaucus, N.J.  This important milestone comes only five years after Equinix opened its first IBX center on July 27, 1999 in the Washington, D.C. area.

New York magazine will utilize Equinix's New York center to host the
publication's Web infrastructure, moving these operations from the data
center of its former corporate parent company to Equinix's state-of-the-art
facility.  The move will enable New York magazine to leverage the benefits
of direct access to a variety of service providers as well as Equinix's
secure infrastructure.  By directly linking to the carriers, ISPs and other
networks within the center, New York magazine will streamline its
connectivity infrastructure, moving content closer to end-users.  This will
enable the publication to increase the reliability and performance of Web
operations while reducing the cost and complexity of reaching these
strategic partners in multiple locations.

Equinix provides a secure and reliable data center infrastructure offering
direct access to a large aggregation of enterprises, content providers,
e-commerce companies and network service providers.  The company's 15 IBX data centers, where companies such as IBM, Amazon.com, SBC, Yahoo! and MSN locate their critical IT and connectivity infrastructure, are designed to meet the most demanding requirements of today's businesses.  The centers have become an important element in the infrastructure of the Internet, offering direct access to the providers that serve more than 90% of the world's Internet networks and users.

"The Internet is a key component of New York magazine's brand, with as many people accessing our on-line products as reading the magazine each week," said Joseph Galarneau, chief technology officer of New York magazine.

"Since we had to move our hosting environment due to a change in corporate ownership, we sought a provider that would offer a state-of-the-art, highly reliable platform that would support our aggressive growth trajectory. Based on the positive experiences of one of our sister companies, which relocated to Equinix's New York IBX several years ago, we felt that Equinix would be an excellent partner."

"The fact that an established media company is our 1,000th customer is
indicative of the continued growth for Equinix in the content and enterprise segments," said Peter Van Camp, CEO of Equinix.  "Reaching and now surpassing the 1,000th customer mark is another important milestone in solidifying our market leadership position."
