That link will give you a listing of all the servers and their current status. Right now only one server is up (about to come down according to another post in this forum) so that might account for why so many are having issues.
Dev response earlier said that the website linked was completely inaccurate and has false info.
I love Dev responses like that ... that's great, but it's total cr@p. Well, how about providing something that works then. Drives me crazy at work. We'll all stand around and tell you how what you're doing is wrong and we could do it so much better but no one bothers to pick up a spanner and actually put their money where their mouth is.
