Happened to me from like 2pm EST - 5pm EST. Waiting through the loading did nothing. I sat as long as 46 minutes at one point, just go do something else for a while.
Right now upon log in I have no bank, mail, guild, or friends list. My UI looks all messed up like it was reset and a 4 year old played around with it. Chat logs in guild take several minutes (according to those on vent) and other things are messed up.
Funny how this *** was an issue 8 months ago and they cared more about a 4/4/14 launch than they cared about a polished product. None of this is new... this is stuff we reported on constantly months ago.
I would not be surprised if they bring down the server.... again.
