Edit: Just to confirm; we are under attack again. We are looking into it, and will have a talk with the host about possible solutions, and search some logs and send out some abuse mails. I can't give you any date on when this will be over, as it seems that the attacker don't want to give up the attacks yet.
I ask everyone to have patience, as we're not giving up. Please do not contact FoCo support about refunds or extension of your premium membership until the server is online again.
Thank you for your patience!
Update: The null route on the VPS will be removed tomorrow evening. We will try to finish a new temporary security feature before that to see if it helps against the attacks. More information about this feature will be announced when we're ready to try the server again.
