Yes, my connection works just fine as I'm able to connect to other online cames. I've tried several other locations to rezz at and I still can't seem to get in-world. Though, I did finally get to pop in for a moment, but when I logged out... I was unable to log back in and got the same pop-up again.
I'm starting to wonder if the servers are a little backed up. Maybe too many people trying to get on at once? I don't really know how that works, but it sounds like it could be a possibility.
