BRISBANE, Calif., and LUXEMBOURG CITY, Luxembourg, July 13, 2005 -- UltraDNS™ Corporation, the world's leading provider of Managed DNS services, today announced the further expansion of its global constellation of DNS servers. The deployment of DNS server infrastructure in Luxembourg builds on UltraDNS' major existing European footprint and represents a significant investment in support of Europe's estimated 269 million Internet users. UltraDNS is the leading service provider to the g-TLD (generic) and the cc-TLD (country) community with its industry leading Managed DNS Service™ and has powered the DNS infrastructure for the .lu TLD for Luxembourg since 2003.

"This European infrastructure expansion is a major enhancement of the UltraDNS services and provides additional redundancy and security for the Luxembourg Internet community," explained Antoine Barthel, director at the RESTENA Foundation, which operates the .lu TLD. "We have been constantly impressed by UltraDNS' commitment to the ccTLD community, through its investment in network capacity and superior levels of customer support."

"The expansion of the UltraDNS infrastructure is indicative of the global nature of our service and our customers," said Rodney Joffe, Chairman and CTO, UltraDNS. "As demand for Managed DNS services increases across the world, UltraDNS continues to distribute its technology globally, as more and more countries are turning to our company for the highest level of local resolution and enhanced Internet performance and security."

The UltraDNS infrastructure supports the resolution of over 20% of the world's registered domain names and responds to over two billion queries each day with unmatched DNS resolution performance. Today's announcement follows the recent deployment of an UltraDNS node in Johannesburg, South Africa. UltraDNS is currently undertaking a global expansion of its network, with anticipated future infrastructure deployments in South Asia and Latin America.
