I've been having the same problem for the last 4 hours. Power cycled, rebooted, even did a speed test to see if I was having packet loss on my end. No impacts, nor indication of issues. Results of traceroute below.
Same thing here.... I was in combat with a Romulan vessel and it was suddenly invulnerable. So i try to warp out, and get told that can't be done. Logged out, now I can't get back in with the persistent message "Could not get map names from map manager."
