Transaction Network Services Leverages Equinix in North America and Europe; Expands Managed Connectivity Services to Asia-Pacific

Equinix's clients provided a new, low latency direct access for the financial community to exchanges and execution venues

FOSTER CITY, CA, LONDON, UNITED KINGDOM, SINGAPORE, July 12, 2010 - Equinix, Inc. (Nasdaq:EQIX), a provider of global data center services, and Transaction Network Services (NYSE:TNS), a leading provider of business-critical, cost-effective data communications services, today announced that TNS' Secure Trading Extranet is now offering low-latency connectivity through Equinix's International Business Exchange™ (IBX®) data centers in Australia and Singapore.

This announcement follows TNS deployments in Chicago, New York, London and Frankfurt, enhancing TNS' position as a key connectivity provider for the global Equinix trading community.

The Asia-Pacific market presents significant growth potential to the electronic trading community as Asian exchange volumes continue to grow and as demand for interconnecting multiple venues, participants and geographies accelerates. TNS's network at Equinix data centers helps to connect a global financial community of interest, including buy and sell-side firms, hedge funds, execution venues and suppliers of market data and trading technologies.

The participants of Equinix's financial community will benefit from TNS' global network infrastructure, which provides services to over 40 countries around the world and 1,600 end-points on its Extranet. Both companies' financial sector expertise and the presence of an extensive trading community at IBX facilities will support TNS' objective of rapidly enabling new entrants with an easier access into the Asia markets, as well as connectivity to other markets worldwide.

“Supported by TNS' connectivity, our facilities in Australia, Hong Kong and Singapore become an even stronger platform for both new and current financial participants to build in and use for accessing Asia-Pacific markets,” said John Knuff, general manager, Equinix Financial Services. Our IBX clients can benefit from this new high-performance, low latency infrastructure in addition to Equinix's broad range of offerings, other financial participants and technologies.”

Alan Schwartz, President for TNS' Financial Services Division, said: “The presence of a robust electronic trading ecosystem within Equinix will allow us to increase our connectivity and build on our growing client base. We believe our joint clients will greatly benefit from this new low latency network connectivity, enabling them to capitalize on the improved speed and reliability that is key to today's electronic trading.”
