The google.com, is not blocked in china.....
it is blocked by google, we ran some tests outside of china looking the the DNS resolution and how it was blocked
we found we could get a computer outside of china blocked by google, if we triggered a DNS lookup inside of china.
The addresses returned resolved to addresses inside google over in calafornia data center , but access to google was blocked.
Even for a non China based computer....
So er let's not be blaming China on this one.....
