Having weird issues with loading?!?!

[WaitingforMoP]

I just got loading screen stuck at the middle of entering an arena

Try to log back in, it loads about 80% says something about a character with that name already exists

I try to log in again, it just freezes loading

Try again on a diff char, freezes loading, try again, freezes loading

Try on a 3rd char, freezes loading

I have an authenticator so I doubt it's a hacking related thing.... I'm thinking 5.1 might be glitchy or something?

Has anyone else experienced this today?

Edit : Tried again on the 1st char and got in, still this was odd...

that it did it on multiple characters is odd, but the error you got isn't new - the server just has to wait for your char to timeout.
