If you’re not able to sign into Activision Blizzard’s Battle.net, 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 both on its verified customer service Twitter account, and additionally in a “Breaking News” item you may see if you’re able to partially sign in.
[#BNet] We are currently experiencing a DDoS attack, which may result in high latency and disconnections for some players. We are actively working to mitigate this issue.
