is partially down and Blizzard says it’s a DDoS attack

If you’re unable to sign into Activision Blizzard’s, the online service underpinning Overwatch, Call of Duty: Warzone, Hearthstone, Diablo’s online features and more, that’s because it’s experiencing some significant issues — ones which Blizzard is currently pinning on a Distributed Denial of Service (DDoS) attack, where servers get overwhelmed with traffic.

Blizzard is stating that it’s a DDoS on its verified customer service Twitter account, and additionally in a “Breaking News” item you may see in the PC client when you attempt to sign in.

On DownDetector, outage reports seem to have spiked, with thousands reporting is down but only hundreds complaining about individual Blizzard games losing service. We’re not seeing the typical number of reports we see on Twitter when a game goes down, either, so it seems clear this is not a full outage, and the “high latency and disconnections” are likely not affecting the majority of players.

We’re reaching out to Activision Blizzard for comment and more details.
