Comment (by teor):
There's also this work in progress (not by me):
https://github.com/TheTorProject/bwscanner/blob/develop/bwscanner/detect_partitions.py
Some of the issues I ran into when writing a similar script:
* network load - running these tests as fast as you can puts significant
load on the network
* what if a relay is down, rather than blocked?
* making ~7000 connections through a single relay might overload it,
particularly if it's low-bandwidth, file-descriptor limited, or behind a
NAT box
* connection testing is directional - sometimes relay A can initiate a
connection to relay B, but relay B can't initiate a connection to relay A.
But once they're connected, they can both exchange cells
