Like the (or should I say das) North American realms, European realms will largely consist of rolling restarts with only a few exceptions, which we'll get to in a moment. Rolling restarts will begin at 05:00 CEST and should be finished by 07:00 CEST.
However, there is a set of realms that will need an extended maintenance period that will begin at 03:00 CEST and last until 15:00 CEST. The affected realms are: Auchindoun, Ghostlands, Hellfire, Karazhan, Nagrand, shattered Halls, Sporeggar, and The Sha'tar.
If you're unsure of what these times are in your time zone, please refer to the World Clock.
Should you need entertainment throughout the maintenance period, just take look at Daniel Whitcomb's latest edition of the Tuesday Morning Post, which rounds up our site's best and brightest posts of the week.
