Lately i have had huge problems when connecting to the server, sometimes i can't even get in to the character login screen, and sometimes i can get online but never undock it will say lost connection, and if i am lucky i am able to undock and be happy for like 10 sec before i get this connection lost again, and its not because of many players when i connect its only 50-90 players online. and the strange thing is, that i might be lucky sometimes and actually be able to play for some hours, so this problem is totally random and its getting on my nerves.
See if its with the server or with your connection. Also maybe server is full? As well as today there was several server reboots and seemed like an over all slower connection (from my end atleast).
If you had a good connection before and now don't- 1. Check out link above. And 2. Maybe check it in a day or so, maybe the server is just running slow.
PS- type "/ping me" once your logged in to see your connection/lag as another way to check.
