Today we experienced extansive DDOS atacks on server11 and server15.
There also was an attempt to hack server 15 through insecure YabbSE software with ssh exploit.
While atack on server11 stopped relatively fast. server15 is still under extansive atack. We have to block wide ranges of the ips to keep server protected and it is unreachable from many places. When atack from those ip ranges stops we leaft block.

We leaft blocks once every half hours in order not to risk too much and decreased chances of server being compromised during route restarts.

Sorry for the problems and thank you for your patience.

Looks like atack is over. About 20 minutes ago we put off all blocks.

Please note that because of the nameserversempty answers being cached by some ISPs you may still cannot see your domains.
To se whether this is the case you can try to access your domain by username http://serverip/~username/
If page loads it means that page works for others and will work for you when your ISP will update DNS.

Sorry about inconveniences caused by DDOS atack
