Constant dc´s and server crashes

Hello there,
I was just doing a rhot, and like a couple of times the past weeks, the server just crashes. I´ve counted atleast 5 crashes like this the past week and a half. On top of wich there are constant random disconnects (i can assure you that this isnt a problem on my end, alot of other people from my guild usually get kicked at the same time aswell). Please look into this? It starts to get abit annoying, especially when you get kicked out or the server crashes in the middle of a raid -.-

P.s. Just happened again, neltharion down, pvp server is up.

Cheers
