npc's down

Npc at cruma tower have been down for a while and I can't continue wth my quest not sure if this is affecting other places but can you guys do something about it thanks

i know... go**** bro i can't do anything execpt lvling...
About the kama quest im still waiting for another day till i can kill the raid and finish the quest.

im new to this game but do the gm's take this long to reset npcs (its been about 2 days) or is it because of the holiday weekend.
