Test if any website is blocked in China

I tried github several times and every time it fails to load at least for a couple of the places but it does load intermittently from all of the servers. I wonder what that means - is it being throttled so that it loads slowly? The same doesn't happen with other websites - for example, my website consistently shows ok from all servers.

As someone who travels to China fairly frequently I can say I've found this site to be inconsistent.

That said, different locations within China have inconsistently differing levels of blockage (for instance, you can access many more places from within the greater Shanghai area than from within nearby Hangzhou and can find differences in what is available between Hangzhou and Beijing) so I think it is difficult to definitely state that this or that site is completely unavailable from anywhere within China.

I typed www.facebook.com.

Amazingly, it was the response page itself that got blocked(, TCP reset to be precise). Perhaps the Great Fire Wall read 'www.facebook.com' as a substring in url, and subsequently killed it.

This is because of the different service providers and the decentralization that is applied from within the government.

It leads to inconsistency but it stops some of the mistakes that result from an overly centralized government.

Completely off topic - It drives me crazy when the enter key doesn't submit forms. Especially one liners.
