Gentoo Linux Selects UltraDNS to Deliver World's Leading DNS Infrastructure

Fastest Growing Linux Distribution Demands Increased DNS Performance, Manageability and Availability

SAN MATEO, Calif., June 24, 2003 -- UltraDNS™ Corporation, the world's leading Managed DNS Service Provider, today announced that Gentoo Linux, the fourth largest open source Linux distribution boasting more than 100,000 users, has selected UltraDNS' Managed DNS ServiceT to provide mission critical DNS resolution and enhance the uptime, reliability and performance of the Gentoo Linux Web presence.

Gentoo Linux optimizes users' access to all Internet related services by leveraging UltraDNS' unmatched, globally dispersed multi-networked, multi-node and multi-server directory services infrastructure. UltraDNS' high performance, proprietary non-BIND name server technology not only delivers the highest Internet query response times in the world, but also guarantees 100 percent DNS uptime.

"Our source-based distribution relies heavily upon an infrastructure of mirrors, which in turn relies heavily upon our DNS servers," says Kurt Lieber, Infrastructure Manager of Gentoo Linux. "While we may be the fastest growing and a very well-respected Linux distribution, we knew we weren't DNS experts and that UltraDNS would provide us with a carrier-class DNS infrastructure that allows us to continue with our mission to provide extreme performance, configurability and a top-notch user and developer community."

Gentoo Linux takes advantage of a combination of UltraDNS' advanced services including Directional DNS, Recursive DNS and SiteBacker, UltraDNS' latest service offering. SiteBacker, UltraDNS' monitoring and automatic IP fail-over service, monitors the Gentoo Linux website and in the event of a failure, directs traffic to a "hot" standby.

"We are excited to have Gentoo Linux as a valued customer. They are a prime example of a company that has had marked success based on their best of breed product offering and their mission to provide their users with the highest level of service," says Ben Petro, president and CEO of UltraDNS. "UltraDNS helps Gentoo Linux by eliminating performance and reliability issues inherent with standard DNS deployments."
