Rackspace knocked offline by huge DDoS attack

Hosting and managed cloud provider Rackspace has been taken offline for more than 12 hours by a massive DDoS attack.

Rackspace posted a warning on its official Google+ page stating: “On December 21st, at approximately 23:54 CST, backbone engineers identified a UDP DDoS attack targeting the DNS servers in our IAD, ORD, and LON data centers. As a result of this issue, authoritative DNS resolution for any new request to the DNS servers began to fail in the affected data centres….a portion of legitimate traffic to our DNS infrastructure may be inadvertently blocked. Our teams are actively working to mitigate the attack and provide service stability.”
