Foster City, CA — July 11, 2005 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centers and Internet exchange services, has received a "strong positive" rating in Gartner's recently released "Marketscope: Internet Data Center Colocation, United States, 2005."

The report establishes a new rating system focused exclusively on colocation through criteria that review data centers, network access, product portfolio, service and support, and financial viability. Gartner considers companies receiving a "strong positive" rating to be "solid providers of strategic products, services or solutions" and recommends that existing customers "continue investments" while potential customers "consider the vendor a strong strategic choice."

"Equinix is thrilled to have received a strong positive rating in Gartner's report on Internet Data Center Colocation," said Peter Van Camp, CEO of Equinix. "We feel our steady growth as a company, coupled with this influential rating by Gartner further confirms Equinix's ability to support the growing IT infrastructure needs of today's businesses."
