Equinix Co-Founder and Chief Technical Liaison to Present at Australia’s Premier Telecommunications Event

Sydney — March 7, 2005 — Equinix, Inc. (Nasdaq: EQIX), the leading provider of network-neutral data centres and Internet exchange services, today announced that William Norton, co-founder and chief technical liaison will be presenting at the 21st Australia Telecommunications Users Group (ATUG) to be held in Sydney, Australia from 9-10 March, 2005.

Mr. Norton will provide a glimpse into the Internet core infrastructure, where a recent white paper, "Asia Pacific Peering Ecosystem," suggests that changes are taking shape. Mr. Norton has developed a framework to classify and understand the relationships between the players within each Internet region, allowing them to compare and contrast each peering ecosystem. By helping attendees understand these relationships, Mr. Norton will discuss how service providers and enterprises can adjust their current strategies and succeed in this changing environment.

The first half of Mr. Norton's talk will present this framework, and the second will focus on a few specific disruptions, including mergers and acquisitions in the industry, that are generating changes within the peering ecosystems. This talk will shed light on the dynamics that are reshaping the Internet and examine the implications for both local and global ecosystems.

Mr. Norton researches large-scale interconnection and ISP peering, and in particular, scaling Internet operations using optical networking. He has published and presented several white papers, including "Interconnections Strategies for ISPs," "The Peering Simulation Game," "The Art of Peering: The Peering Playbook," and "The Asia Pacific Peering Handbook." Norton has also chaired the North American Network Operators Group (NANOG) Internet industry forum and has been an active member of the Internet Engineering Task Force for the past 15 years.

Equinix is a major player both in Sydney and overseas in peering infrastructures, data centre and co-location services, with over 15 peering customers in their Sydney IBX Centre. Equinix is expected to become the leading global player in co-location services by 2006, according to U.S.-based Tier 1 Research.

In its recently released 2004 results, Equinix reported adding 69 new customers in the fourth quarter and 324 customers for the year 2004. The company received additional orders in the quarter from approximately 50% of its existing U.S. customers including Doubleclick, Merrill Lynch, Ticketmaster, the U.S. Government and Yahoo!
