The european Battle.net servers have had huge disturbances for several days now, causing disconnects and other unholy nuisances. This is due to a fiber cut at their subcontractor Telia. Five days and counting.
Due to technical issues, World Of Warcraft , Diablo 3 , Starcraft 2 , Hearthstone and Heroes Of The Storm players may experience latency or loss of connection. We apologise for any inconvenience this may cause and thank you for your patience while this is being resolved.

The games are playable as of yet, but disconnects are pretty frequent. I myself were the victim of one when playing Heroes of the Storm. I was dropped about 15 minutes in, had to wait 10 minutes for a reconnect, and went back in time for the victory screen. Luckily the AI could handle itself.
