Thanks for reporting this.
Servers are now up.

I was just having the same problem for a few minutes, just tried again after seeing it said servers were back up and now they seem to be up. There are a few that are still not working though, #'s 3, 15 and 16 seem to be down.

Some servers might be down for a while.
Please play on one of the other servers.

Sorry for the inconvenience.
We're working to fix this.

They were up but went down again while I was playing. I can't play the other servers because they are clan servers and I am not a high enough belt.

There's no belt limitation on most servers.

Edit: Servers are up again.

lol xD i can study well :P i hope i can play now :3
