Re: Block directory authorities, is it possible?



You can get a list of servers from a friend or online and manually
import them into tor. Also, you might want to consider anonymous socks
servers to route your traffic through that Golden Shield couldn't
block.

You are correct that this is a vulnerability now.  We're developing a
blocking resistance strategy that should ameliorate this
risk.  Perhaps one of the developers will comment on this further.
