Attack on InterNetX’s DNS servers
As a spokesperson for InterNetX told The H's associates at heise SecurityOn, on Wednesday, a severe distributed denial-of-service attack (DDoS) nearly brought down the German company’s domain name service. The spokesperson added that the firm was still trying to understand the type and scope of the attack.
Around 1 PM CET on Wednesday, domains hosted at InterNetX were difficult, if not impossible, to reach. The host has since added technical filters to mitigate the effect of the attacks; the service is now basically back up and running. Sometime today, the firm hopes to make public details of the attack.
Since 2004, InterNetX has been a part of the United Internet Holding. The firm says that it currently hosts some 2.9 million domains in addition to Schlundtech's domain reselling business. A spokesperson from 1&1 said the problem did not affect other domains hosted by providers within United Internet, such as 1&1 and GMX. InterNetX’s DNS servers were also under a massive DDoS attack at the end of 2008.
