I actually sent an email offering to help (I have a lot of experience mitigating DDoS attacks) but never received a reply. I imagine they must already have something in the works to resolve this.

Just curious, how are DDoS attacks mitigated?

Depends on the attack and how sophisticated it is. For most layer 7 attacks like this one, you can filter e.g. specific user agents or protocols. One thing that often works (but has some false positives with simpler search engines) is dropping all HTTP/1.0 traffic, because any remotely modern browser uses HTTP/1.1. Essentially you block anything that's unusual, like specific user agents (reflected attacks from user agents containing 'Wordpress' and 'PHP' come to mind a lot especially), HTTP headers, and so forth. Ideally as far upstream as possible, but it can be done on the server level as long as you have enough horsepower to throw at iptables or the web server, and your connection doesn't get saturated. The right IP blacklists can help a lot as well.

Could you give a report of the statistics of the IP address in the DDOS attack? Maybe you can block all the ip address from China. As I known in China people have to use VPN to access some sensitive websites (such as 8964, falungong, dajiyuan).

I think a lot of people already did this (including me) and they're probably flooded with offers. Thanks for the support though, I'm sure they're happy about any they get. It's about time to demolish the great firewall of China. :-)
