Can you reach i18n.com?

No - if a govt firewallis going to block a site, why is it in their interests to tell you about it?

Yes, I have a story on i18n.com to post about that later today.

Doubtful at this point.

But you don't really know you are blocked - the first test I would run is do a traceroute and see if/where the request fails.

Then, I would do a "host [ip address]" where ip address is the last ip that shows up in the traceroute, to find out who owns that IP address.

Next test is to do a telnet to the server on port 80. 

Then, if you can, telnet to a different shell account outside china and try the same tests.
