Mmm i tested it now and it seems ok i got there. Maybe you need to clear cache and inventory cache in firestorm viewer and clear cache in singularity viewer.

I'm trying to get there too and says "unknown."

I'm there now. The region does do restarts now and then so you may have caught it during one of those. Also, try typing in just worlds.quintonia.net:8002 as that should also get you there.
