Website Test behind the Great Firewall of China

Test any website in real-time to check if it is accessible from China. The Golden Shield Project (a.k.a. Great Firewall of China) is owned by the Government of China (MPS) and was started in 1998. The firewall system blocks website content by preventing IP addresses from being routed through and consists of standard firewall and proxy servers at the Internet gateways of China's ISPs. The banning of websites is mostly uncoordinated and ad-hoc, with some web sites being blocked from one city and the same web sites being allowed from other cities and vice versa. (You can find more details here.)
Check your website from the following cities in China: Shanghai, Beijing, Guangzhou and Hong Kong.
