Yeah, something is weird with the servers today. The game is playable - sort of - but I've had to restart three times because I was stuck in hyperspace 2x, and in supercruise 1x. For what it's worth, both hyperjumps and SC still mostly complete without having to restart, there's just no guarantee for it. It seems to be more reliable in Solo than in Open play, but it could just be coincidence as I switched shortly after experiencing problems.
Right now I can't sell my cargo at the port, however, always getting a "cannot complete transaction" error (restarted 3x, no dice). I guess I'll just try again in a few hours and do something else in the mean time.
Good luck fixing this, whatever 's the cause!
