ULTRADNS PROVIDES DNS INFRASTRUCTURE FOR THE UKRAINE

.UA Top-Level Domain Increases Geographic Reach with Global Network Presence

BRISBANE, Calif., June 3, 2004 -- UltraDNS™ Corporation, the leading provider of DNS infrastructure for the Top Level Domain (TLD) community, today announced that it has been selected to provide global DNS services for Hostmaster Ltd., the organization responsible for operating the .ua country-code TLD for the Ukraine. The UltraDNS Managed DNS Service allows the .ua TLD to expand its global network presence while providing the network diversity that it requires.

Utilizing UltraDNS technology for the root infrastructure of .ua enables the TLD registry to improve service levels and reliability as it supports the 20% year over year growth of .ua domain name registrations. UltraDNS not only provides the .ua TLD with the software code diversity it requires but also enables the Ukraine to leverage a global network of server nodes located across three continents. This network footprint enables .ua to take advantage of the economies of scale associated with the UltraDNS platform while reducing the operating costs which would have otherwise been incurred as a requirement of running the TLD registry.

"In an effort to provide our user community with the highest level of service, .ua turned to UltraDNS to provide 100% reliability and minimize downtime through a geographically distributed network", said Dmitry Kohmanyuk, director of operations for Hostmaster Ltd. "By relying on UltraDNS for global DNS resolution, our team is free to focus on managing the other operational requirements of the TLD registry."

UltraDNS currently supports more than 25 TLD's and manages the DNS for over eight million domain names. The non-BIND Managed DNS Service™ utilizes advanced routing technology ensuring that the closest available server in the UltraDNS global network answers all user requests. These innovations translate to improved performance and resiliency and contribute to the ability of UltraDNS to guarantee 100% network availability with its industry leading Service Level Agreement (SLA).

"We are pleased to support the Ukrainian Internet community with UltraDNS technology", said Michael Guglielmi, vice president of corporate development for UltraDNS. "As our global TLD base continues to grow, service providers from around the world are quickly realizing the tangible benefits of our managed services and the impact they have in reducing operational costs while providing an increased level of service."
