UltraDNS Service Knocked Offline by DoS Attack

Carolyn Duffy Marsan writes on NetworkWorld:

NeuStar confirmed that its UltraDNS managed DNS service was knocked offline for several hours Tuesday morning by a distributed denial of service attack.

"Early this morning, our monitoring systems detected a significant denial of service attack, which affected a small subset of our customers, in some cases for as long as a few hours," the Reston, Va. company said in a statement. "While we continue to investigate the cause, the extent, and the duration of the attack, service was completely restored by 10 a.m. EST."

NeuStar is a leading provider of high-availability DNS services to e-retailers including J.Jill and Diamond.com as well as high-tech companies such as Oracle and Juniper.
