Blizzard's set to take Diablo 3's US servers offline for maintenance today, following yet more server troubles and dreaded Error 37 appearances overnight. For those who haven't been on Twitter this week, the long, long-awaited sequel finally launched on Monday night, before crumbling under the pressure of players attempting to activate their copies online.Subsequent error messages prevented many from logging on to play, and the troubles have continued every night since. Last Night Blizzard was even forced to release an apology admitting, "our preparations for the launch of the game did not go far enough" The firm's confirmed it will be performing "scheduled maintenance" on the Americas region servers from 5:00 a.m. PDT until approximately 7:00 a.m. PDT today. On Tuesday the World of Warcraft developer told told fans who still can't log on to the game to "wait and try again". On the review front, we're still not quite ready yet (insert login joke here) but you can stick your eyes on Andy Kelly's verdict on the first ten hours of Diablo 3.
