Connection issues

ive finally found a server i like, this one.

however i repeatedly get connection issues in that when i connect i can only get around 10 minutes of play in before i get the. Connection lost, attempting to reestablish, error message. at which point i am thrown back to the main menu. so i think oh well ill log back in again, now i get error connecting to server and when it does at last work i am apparently still logged in??

whats going on is it my computer or a server issue??
