It is a problem with server 1&2 communication
Since the character vault is stored on server1 and your destination (NScity)is on server 2 your character is probably in limbo with the rest of the characters that logged out on server2 (as in both of mine

)
Although I am not one of the developers so I can't be sure. For all I know server 2 is actually on fire and DD is franticaly beating it with a wet kitchen towel ...
