Announced head of time by group, timing matches up, there is a visible attack going on seen on two ddos tracking sites, the style of attack matches up previous attacks by the same group, done on days where there was no other reason it might have happened - group has also successfully called attacks on Steam, Guild Wars 2, WoW, Aion, Lineage and other games like LoL.
So while it *might* not be them, and just the usual Christmas traffic... it could also be an attack taking advantage of an already congested system.
Right on, thanks for the knowledge.
