OK, I know what the problem is with people logging out.
Looking at this map again:
You can now directly connect to LFGSS from all of those cities (without going over the public internet).
The issue is that vBulletin (which powers this site) uses the IP address of the connection as the hash for the session cookie.
So if, as a result of network conditions, the route of the traffic somehow switches to another city... then the IP address will appear different and it will invalidate the session cookie, thereby logging you out.
I'm investigating right now how to solve it.
