Ok so I havent benn able to get onto WOW lately for some odd reason, Im able to get on my character but when I get to the loading screen it always go's through the bar quickly and I get disconnected from the server. Has this happened to anyone? my connection is fine!

nope. I suggest running the file check included with the game...something is not right. or call blizz..

The closest I've been getting to that is I get disconnected when I leave Undercity via the elevators (and once entering Undercity via the elevators).

Yeah Hunter that use to happen to me, the elevators are kinda crazy, that's why i fly =D

And the Disconnection problem i also use to have. Did you ever install a second WoW folder? I had it working fine than when i quit for a while and deleted some of the folders. Once i wanted to play again i reinstalled into a new folder which cause crazy things so i have to delete the other folders and also make sure if this is your case to use THE NEW WoW launchers so it doesn't cross the folders, someone correct me if i'm wrong but once i did this it worked like nothing ever happened.

It worked again today i think it may be on their side, not mine.

Mine worked again today as well, hopefully it wasn't just a one-off case. I think blizzard had realised people were experiencing connection problems and fixed it.
