I'm on a server in Austin, Texas at the moment. If you want to find your server location simply type /ip in the command line in game. Type that ip into an ip address finder such as
http://www.ip2location.com/free.asp which is free and that will tell you where the server you are connected to is located.
Hope that helps although it only tells you which server YOU are on and not anywhere else. I guess if people from different countries posted where they connect to then we could get a better idea where the world wide locations are..
Anyway, here's my input.
Live in Australia. On US server 216.107.245.90 is in Austin Texas
Ok. I did some hopping around and found that a particular location had a particular ip. The one i mentioned was for Umbral Grotto. 216.107.245.93 was Olafstead. So I'm guessing they run at least one server per town and maybe more for the busy cities. When i moved to International district I stayed on the same ip range but in Umbral grotto I moved to 216.107.245.117. So I wonder if people could trace there ip location and see how many server locations there are around the place.
Just for fun
