Apparently, our Minecraft host Shard Gaming is [blink]bankrupt[/blink]. What this means for you: NO MINECRAFT SERVER FOR AT LEAST A WEEK UNTIL I FIND ANOTHER HOST.
It was neither for me. It was just weird. There was no warning or signs that the company was in trouble. They just sent an e-mail that I needed to make a backup immediately, since they didn't pay their co-location bill, and the server could be shut down at any moment. Also, no communication possible with them. The e-mail server bounces, and they deleted their Facebook, Google+, and Twitter accounts.
