Indosat to Establish Network Operations at Equinix Singapore Data Center

Singapore — May 18, 2005 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centres and Internet exchange services, today announced that PT Indosat Tbk, one of the leading telecommunications providers in Indonesia, has deployed a network Point- of-Presence (POP) within Equinix's Singapore Internet Business Exchange™ (IBX®) centre. By hosting its infrastructure at Equinix's Internet hub, Indosat plans to enhance service to existing customers by streamlining operations and directly connecting with the aggregation of networks operating within Equinix's Internet hub.

Equinix's network-neutral business model provides a strong platform to serve Indosat's need to directly interconnect to multiple global network service providers. The close proximity to key networking partners within the same physical location, as opposed to connecting to them in multiple, disparate locations and across great distances, will enable Indosat to streamline its network connectivity and greatly reduce intermediate transit. As a result of the deployment, Indosat is also better positioned to increase business opportunities.

"As the leading telecommunications provider in Indonesia, we have set a high standard for the service quality that our customers receive," said Mr. Samsriyono Nugroho, General Manager, Carrier Relations of Indosat. "We are continuously improving that service through carefully planned moves and strategic partnerships. Equinix fits into our business model with its industry leading data center infrastructure and unique network-neutral model."

"The addition of Indosat to the aggregation of networks operating in Equinix's Singapore hub contributes to the growth of our regional carrier community and enables other Equinix customers to leverage direct access to another leading regional network," said Mr. Lee Yoong Kin, Managing Director of Equinix Singapore. "In addition to Equinix's colocation and Internet exchange services, we have recently launched other managed services offerings aimed at helping our customers in the Asia-Pacific region to maximize their IT operations."
