Activision Blizzard said on Twitter Wednesday that its Battle.net service was suffering from a Distributed Denial of Service (DDoS) attack. A little over an hour later, reported that the attacks it was monitoring have ended.
In the initial tweet, sent at 7:11PM ET from the @BlizzardCS Twitter account, the company cautioned that the attack “may result in high latency and disconnections for some players.” That first tweet mentioned a singular attack, but a second one reporting that things had ended, sent at 8:29PM ET, referenced attacks — plural.
[#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.

Based on user reports on Downdetector, players were having issues with games including Overwatch, World of Warcraft, Call of Duty (though exactly which title isn’t specified) and Diablo III.
Battle.net experienced DDoS attacks for about an hour in November that similarly caused problems for players trying to play games.
Update May 11th, 8:39PM ET: Activision Blizzard says the attacks it was monitoring have ended.
