Zul’Gurub, Ruins of Ahn’Qiraj and Onyxia’s Lair are all broken.
There are no bosses in them. A reset for these raids occurred yesterday, bringing the trash back, but the bosses are still not there. This problem began with the pre-patch a couple of days ago.
Additionally, when looking at the raid reset scheduled in-game, the raids have a note saying they will reset, but the area where the time/date of the reset is supposed to be is blank.
Not sure why this hasn’t been higher up on the ‘to fix’ list given its content in the game that’s no longer functioning.
