This is the message from the host:
This was null routed due to the following:
Exceeded Bits In: 5 G (Threshold: 1.5 G)
Exceeded Packets In: 457.1 k (Threshold: 150 k)
Due to the size of the null route it will need to remain null routed until the system rechecks this in approximately 1 1/2 hours.
Update: Server is up for now. Can't guarantee that we'll be up for long, but enjoy while you can.
Update 2: There is nothing I can do about the downtime at the moment.
