There is some confusion as to whether the problems that WoW players faced over the weekend was "routine maintenance" as was claimed by Blizzard Entertainment, which runs the game, or a denial of service attack.
The first reference to an outage was when Epifanio', Senior Game Master, told the forums that Blizzard's ISP, which is AT&T, was having some 'significant complications'. As a result the playability on a large portion of realms has been adversely affected, Epifanio said.
This announcement was followed by some "emergency maintenance outages". It seems a little strange that when you are having problems with your ISP to suddenly stop for a bit of server maintenance of your own.
The Netcraft logs for the WoW servers show a pattern which looks remarkably similar to a DoS attack, at least according to Netcraft.
It would not be the first time a MMORPG game has been walloped with a DoS attack. Final Fantasy XI has also been hit before.
More at Netcraft. ยต
