game can't read realm server frost wolf

[se3aa]

I was playing wow MOP then I shut down my pc .. after 4 hours I go to pc and turn it on and opened game to play but I found that frost wolf not existed in game intro = no communication between my game and realm server so I can't log in .. any help for this problem ( sorry for my English )

There was an update recently so they restarted realm. It started again but crashed after some minutes and still is down.
P.S. I can enter now.

I still can't enter .. game can't read realm server.. GM told me to ensure that SET realmlist "logon.warmane.com" in the third line and I did .. it was deleted and I added it then I tried to open game but I found same problem
