Well, Tor will finally recover here when the fibers are repaired. But
this reminds me of a possible attack against the Tor network, say, if
the notorious Great Firewall of China blocks *all* the connections to
*all* the directory authorities (currently 5 I believe), then Tor will
will become completely useless in China. Considering the number of
directory authorities, this doesn't seem to be infeasible. (In fact, I
think this is easy to some extent.)
Am I understanding correctly? Are there any actions Tor can take? After
all, we cannot simply assume this will not happen in the future.
