From this link http://forum.warmane.com/showthread....rations/page19 Proterean stated a manual extension of event for Ragnaros and Death wing, but it seems the event ended according to schedule :/

We are not feeling confident in the fix so far and from internal testing we believe it might cause further issues and it requires detailed monitoring on the live realms, therefore we need more time to make sure this won't cause more chain crashes. Don't worry though, for all the time lost, we will manually extend the events for Deathwing and Ragnaros.
