Blizzard Entertainment’s Battle.net service was the target of a Distributed Denial of Service (DDOS) attack this past evening. Customer service agents announced the service distribution on one of the company’s official twitter accounts.
Users reported connection problems with games like Overwatch on Reddit, with several posts being unable to even sign-in to the Battle.net launcher. Over the course of this outage our staff noticed considerable lag and matchmaking issues with Overwatch as well.
The entire attack lasted roughly seven hours – at least that the time difference between Blizzard CS announcing the attack and sounding the all clear.
[#BNet] We are currently monitoring a DDOS attack against network providers which is affecting latency/connections to our games.
