I'll just confirm that I'm having the same problem. Started within the last hour. Prevents any transfer between maps (sector block to sector block, sector block to system, planet to space within a mission, etc.) Either sits at load screen and then times out, or just crashes after 10 minutes or so.
I've tried five times in the past hour to enter a map from sector space and after waiting five minutes on the "Loading..." screen I am finally kicked out to the log in screen, where I see the following message:
Timeout while waiting for gameserver address
I've been experiencing really poor server reponse time over the last few days. Mainly since the big Season One patch.
