I recently wrote that web site owners and bloggers could choose to block China-based internet users--as a form of protest to government censorship.

And GoDaddy.com now routinely blocks both email and HTTP requests from China, leaving many foreigners who live in China but host their websites with GoDaddy with frustrating connection issues.

I help represent Spamhaus in China and I routinely run across smaller ISPs in Europe and America who block Chinese users’ access to their hosted sites. Much of this blocking is ad hoc and based on the individual sysadmin’s “preferences”. Often they will block all IPs registered via APNIC to Chinese companies, or they will block email based on any .cn domain name suffix in the email headers–anywhere in the headers, mind you, even if your message just took a single hop within China.
