Replying to [ticket:2576 arma]:
> Ticket #1851 suggests reprogramming bridges to connect to baidu
periodically, and then report the reachability results in their extrainfo
descriptors. We'd have to specify how that reporting works, how often the
tests happen, whether we should generalize to write "baidu.com" in the
consensus, etc.

> A much simpler approach would be to build a circuit to the bridge,
extend that circuit to baidu.com:80, and then look at the failure error
code and discern whether it was reachable and just didn't TLS right or
whether it was unreachable.
So Tor bridges, and ''only'' Tor bridges, will try to open TLS connections
to baidu.com:80? Do I really need to tell you that this is a bad idea?
