It looks like it won't be any raid during wednesday, cause of an extended maintenance. We can always hope for a miracle from Blizzard. :P

In addition to our scheduled realm maintenance tomorrow, Wednesday, 18th October, the realms listed below will be undergoing extended maintenance as part of our ongoing hardware upgrades. We expect a total down time of 36 hours. This maintenance will start at 05:00 on Wednesday morning and is scheduled to finish at 17:00 CEST on Thursday, October 19th.
