Comment:

 I built a small golang service that lets bridge operators test their obfs4
 port. For now, the code is available at
 https://github.com/NullHypothesis/obfs4PortScan.

 I set up a demo at https://nymity.ch:8081. After entering your bridge's IP
 address and port, the service tells you if the port is reachable or not.
 If the port is unreachable, the service tells you the error message it
 got. The tool also has a simple rate limiter that limits requests to an
 average of one per second, with bursts of up to five per second.

 What can we improve?
