December 25, 2007

A distributed denial of service attack struck furry art archive Fur Affinity and image boards E621 and Fchan on Christmas Day 2007; which was a Sunday, lasting for several days. Fchan suffered from degraded functionality until early Monday morning,[1][2] while Fur Affinity's main site was mostly unusable until the evening of the same day.[3] E621 had returned by the middle of the week.[4]

The initial burst of traffic was via UDP, a protocol not typically used by web servers, but blocking such traffic only worked for a short time.[5] During the downtime, Fur Affinity popped up sporadically, with users reporting abnormalities such as getting logged in under other user's accounts.[6]
