Yet again I cannot connect to skyblock.net. Get a java error with no further info. But according to website the server is up an running??
Well you're not banned pman, so it must just be an issue with minecraft right now. Just be patient and try again in a bit.
Cypriot said something about how they upgraded yesterday. I don't have full details, but basically you have to wait for your minecraft to update. This shouldn't take too long, alot of players minecraft already has. As PeinRii said, just be patient.
