Battle.net has recovered from DDoS attack, Blizzard says

Blizzard says that the Distributed Denial of Service (DDoS) attacks that were overwhelming its servers with coordinated traffic are over, and that you should be able to log into Battle.net again. During the almost hour-long Wednesday evening attack, you may have experienced serious issues trying to get onto the online service underpinning Overwatch, Call of Duty: Warzone, Hearthstone, Diablo’s online features and more.

Blizzard stated that the issue was caused by a DDoS on its verified customer service Twitter account, and additionally in a “Breaking News” item you may have seen in the PC Battle.net client if you tried to sign on during the attack.

Users that did manage to sign in may have been placed into a queue that warned of high traffic, like this:

On DownDetector, outage reports spiked across a number of Activision Blizzard properties, with thousands reporting that Battle.net was down, but only hundreds complaining about individual Blizzard games losing service. We didn’t see the typical number of reports that crop up on Twitter when a game goes down, either, so it seems clear it wasn’t a full outage, and that the “high latency and disconnections” likely didn’t affect the majority of players. The outage reports seem to have more or less returned to normal levels.
