Following today's maintenance and the continuing rocky launch of Warlords of Draenor, Blizzard has announced another round of extended maintenance for November 15 on North American realms. According to the Battle.net launcher, realms will be taken down at 3:00 a.m. PST and Blizzard expects to have them up again at 9:00 a.m. PST.
We do hope these launch issues are brought under control soon. Saturday maintenance is, historically, highly unusual -- and not very convenient for players. As necessary as it may be, extended weekend downtime is a hard sell for a brand new release.
