Two DNS servers hit by denial-of-service attacks

28.03.2006
In the second attack of its kind in the past few days, Domain Name System (DNS) servers at Network Solutions Inc. were hit by a denial-of-service attack Monday, resulting in a brief performance degradation for customers, according to the company.

The attacks, which started at around 2:20 p.m. EST, were targeted at the company's WorldNIC name servers and resulted in a service degradation for about 25 minutes before the server was restored to normal, a spokeswoman for the company said.

A Network Solutions spokeswoman declined to say what measures the Herndon, Va.-based company took to mitigate the attack.

Over the weekend, Joker.com, a domain-name registrar in Germany, was hit with a similar distributed denial of service (DDoS) that disrupted service to customers.

In an advisory posted on its site, Joker said that 'massive' attacks against its DNS servers had affected the DNS resolution of Joker.com as well as domains belonging to its customers.

Beyond apologizing to customers, the company offered no other details on the attack except to say that it was 'working hard' to find a permanent solution to the problem.
