Thanks. They do not use DNS-based blocking. I will try using the HEAD method if I find a way to do it anonymously.

  If you have the option writing it to look for instances of US blocking that only incidentally finds local censorship may give you some ass-coverage.

  Be careful, I don't think there would be a good way to do this anonymously without distributing the workload.
