Blizzard is suffering log-in issues for games like Hearthstone and Overwatch

Something is going wrong over at Blizzard.
Players are unable to log into the company’s online games, which includes hits like Overwatch and Hearthstone. This is especially bad timing for the digital card game leader, as its latest expansion, Journey to Un’Goro, launched just last week. Blizzard has acknowledged the issues on Twitter.We're currently investigating an issue affecting our authentication servers, which may result in failed or slow login attempts. #BlizzCS
