Test if your website is blocked in China

1) It's down

2) Where is it testing from? Being blocked in China isn't binary; the great firewall is intentionally leaky. There are a lot of sites you can get to from western hotels that you can't from cyber cafes, for example.

I wont trust it a lot since it says torproject.org is not blocked anywhere in China http://viewdns.info/chinesefirewall/?domain=torproject.org
