Been having this issue as well ever since the DDoS thing or so yesterday.
I'm from sweden and playing on Excalibur.

Last thing I did was, stupidly, go to Querrymill and instantly got the 90002 error.
After that, as soon as I logged in I got the 90002 error, tried it numerous times and couldn't get out from there.

Tried connecting via a vpn with the endpoint in usa, now it worked fine and I were able to teleport away from there.
So the issue most definitely lies in where our traffic is coming from, I wouldn't be surprised if this is caused by their anti-ddos measures.
