Tarrenmill Random crash rollback

Tarren mill went randomly down and no one could log in (guild included, at 6:30 US CT, or about 1:30ish Server time) and I lost progress on my weekend event, I had completed 11 quest, but the server booted me out and changed it to 10. Can this please be fixed or looked into what happened? I’m not to worried about the quest progrès, but the server rolling back like that on only TM is highly concerning us.
