Unable to connect Neltharion

Hello,

I am attempting to login into cataclysm neltharion. For some reason, it is just stuck at Connecting then proceeds to show "unable to connect, please try again later, etc.". Is this server side problem? I login everyday and there are no issues. First time happening.

Also, anyone else having this problem at the moment?

Thanks

If that has never happened to you I would try again later before modifying configurations or changing other stuff.
