Obfsproxy Tor Browser no longer works in China
a few days ago I got Obfsproxy Tor Browser https://www.torproject.org/projects/obfsproxy. It worked fine at first. But today I found out it no longer works.

I didn't have a private obfs2 bridge at hand. So I cannot tell if it was because GFW staffs got the Obfsproxy Tor Browser as well and banned all its bridges in its configure. But it's possible because there are few obfs2 bridge in public.
