Equinix to Offer Expanded Peering Coverage to Melbourne and Brisbane Businesses through Agreement with Nextgen Networks

Sydney, Australia — December 6, 2005 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centres and Internet exchange services, today announced the expansion of the Equinix Exchange service to Melbourne and Brisbane, enabling Australian network service providers and content companies to leverage the cost and performance benefits of Equinix's network-rich Sydney Internet Business Exchange™ (IBX®) centre without a physical presence in the centre.

The expanded Equinix Exchange service will be offered by Equinix through an agreement with Nextgen Networks, a leading provider of high-speed end-to-end network services and facilities to carriers as well as corporate and government enterprises in Australia. This service will offer a high-performance network interconnection that will enable companies in Victoria and Queensland to directly connect to carriers, Internet Service Providers (ISPs) and other network service providers operating within the Sydney IBX as if they were located in that centre. Equinix will offer a variety of peering port access solutions dependent on customer's needs.

The service will provide Melbourne and Brisbane ISPs and content providers with cost effective and efficient local connection from which they can reach strategic partners within the Sydney IBX. This streamlined connectivity will improve end-to-end network performance reducing latency and packet loss as well as lowering overall IP transit costs. Existing Sydney IBX customers will also benefit from gaining immediate access to over 80 network and content partners in other major Australian business centres.

Equinix's Sydney hub offers immediate and direct access to leading carriers, ISPs, network service providers, enterprises and content providers within its Internet ecosystem.

“This new service is designed to expand the coverage of Equinix's unique peering service that leverages a critical mass of companies operating within our Sydney IBX to a broader scope of service and content providers in Melbourne and Brisbane,” said Doug Oates, Managing Director of Equinix Australia. “In addition to offering new opportunities for companies in Melbourne and Brisbane, this agreement will also provide significant value to our existing Sydney IBX customers by giving them a broader scope of ISPs and content providers in key Australian cities with which to interconnect."

“This is a great opportunity for Victorian and Queensland ISPs to take advantage of our state-of-the-art network and Equinix's peering exchange to improve their business and offer their customers superior Internet connectivity while improving their cost base,” Mr. Peter Harrison, Nextgen General Manager.

Peering is a fundamental element of the Internet's infrastructure that improves the performance of the Internet for all users by enabling data to pass from one network to another without intermediary networks or bottlenecks. Increasingly, as pressure builds to lower costs while improving network performance, peering has become an essential element of most network strategies.
