Tor Authorities reachability testing is predictable and sequential
In the tor network, all tor authorities test reachability in the same, predictable sequence. Each authority uses the same sequence, and, if started at similar times (a 10 second window ever 1280 seconds), they will start at the same point. (This is a particular issue with test networks.)
I'd like to randomise the start point and progression of the sequence, while keeping the property that each 1280 second cycle tests all routers.
