What is up with the server

You may have noticed that the site was inaccessible for certain periods these past two days. Unfortunately, we got DDOS'ed; I thought that it has been fixed when it happened yesterday, but then I eh, forgot to save the iptables and rebooted the server later the same day. So...back they were again overnight today. it should be fixed hopefully. Please also see this post. Thank you for your patience!
