"DNS queries for web sites should be responding normally. Thank you all for your understanding. As always, we will continue to work to take measures to prevent these and other types of technical issues caused by third parties that may impact our customers."

Network Solutions is having problems with "all" its name servers, according to their tech support and a recent post on North American Network Operators' Group (NANOG) mailing list indicates that it has been under very large-scale UDP/53 DDoS attack for the last 48 hour period. As a result, domain names hosted with Network Solutions' Worldnic have been affected.

Network Solutions is one of the leading domain registrars and DNS hosting providers in the world, managing more than 7.6 million domain names.

The update is: There is a spike in DNS query volumes that is causing latency for the delay in web sites resolving. This is a result of a DDOS attack. We are taking measures to mitigate the attack and speed up queries."
