I was looking in to some office network issues here in Beijing, and the morons are actually using an upstream DNS without going through a VPN...
It's well known the Chinese Firewall poison DNS, but I had never looked in to what they're actually poisoning it with. I've got to applaud them for their creativity though!
It looks like they're basically pointing Google properties to Facebook IP addresses, Facebook properties to Twitter, etc.
At least those guys can handle the extra traffic :)
