I just found out that our site www.eve-rave.ch is censored by the Great Firewall of China Under http://www.greatfirewallofchina.net/test/ you can check if yours is blocked too. For example digitalpoint.com is not blocked. I think it is good tool if you decide to make business in China.
It's reporting my main site as blocked even though I see dozens of Chinese IPs in my stats for today. Anyone know if there is just one database of blocked sites or whether it might be different in various regions of China?
Well there are means to bypass the firewall, and also the special administrative regions of Hong Kong and Macau have their own legal systems, so censorship does not apply there.
On the website it says that a website "...may be reported as blocked, while there are only technical reasons for it's unavailability". My advice would be to try again later.
