Oh dear, I have just encountered the same issue leaving a mission in the B'tran cluster. I was going to head to a bank so I could check a bug reported, someone said that you can no longer withdraw or deposit items in fleet banks, but I can't confirm it right now because the server is not responding.
Add me to the list. I was entering K-7 when i got the first timeout. After loggin in again, i was on the K-7 system / space map. Then i tried to beam down to the station of corse, and then got my next server timeout. I assume when i loggin again, it will work and i find myself on the transporter plattform in K-7.
Edit: Yes, it worked. Now i am on K-7. So the server timeout seems to happen only at map-transfers.
