Hey you can try again to login.
The server was reopened a few minutes ago.
But everybody received silk now so all are spamming globals.
Stupid newbs.
The server crashed 10 seconds ago because of the spam.
Now everyone is waiting for it to open again

Answer to ur question:
They IP-banned 80% of the server to make sure it doesnt crash because of the laggs people create.
The bans are now undone again so you can login again.
