Blizzard is set to take Diablo III’s servers offline for maintenance today, following the reappearance of the Error 37 message preventing players from logging in.
The maintenance will occur – and has probably already happened when you read this – on the America’s region servers from 5:oo AM PDT until 7:00 AM PDT. It shouldn’t bother too many players unless your going for a world first or something like that.
This just adds to the tirade of issues that have hit the game since launch. Blizzard has really been caught off guard by how many players the game has had, hopefully it will be stable by next week.
Have you occurred any connection issues over the last few hours?
