Cannot login to the Icecrown realm as a premium user

Hello,

I can't login to the Icecrown realm today, I can login to Lordaeron and Blackrock realms but not Icecrown, is anyone having the same problem?

same here... for about 1 week... and from today, i cant join another realms also

Fixed, it was peerblock software (using it many years, never a problem), need to be disabled, allow HTTP isnt enought
