Hi Tom et al,
I hope I'm not too far off topic here:
Nope!
I remember from the last tor-dev meeting there was some discussion about replacing the old torflow code with bwscanner a project that Aaron Gibson started and Donncha subsequently worked on. But since there I haven't heard of any progress on that.
No. AFAIK the code is still at https://github.com/TheTorProject/bwscanner.git and waiting to be tested. I intend to test it 'soon' (f a value of 'soon' that might stretch into 4-5 months) and see how its results compare.
Also I have recently done a few small scans for 2-hop circuit connectivity and shared some of the results with Roger on #tor-dev. One theory is that many of the circuit failures are due to traffic spikes at certain hours of the day.
I was thinking that many of the relay to relay connectivity problems could be fixed by adjusting the consensus weights or capping their consensus bandwidth... and that this scanning of "network partitions" shouldn't only be an interesting research project but should probably be a part of the bandwidth authority system.
I saw that! Or at least part of it! Awesome work!
Meejah and I were planning to facilitate a workshop/discussion about these and other issues related to scanning the tor network. Are you coming to the meeting in Montreal?
No. Sorry. =/
Your proposal makes sense to me superficially for sure. I don't own torflow really, I just try and help it keep limping along. I'm not qualified enough to say it's a good idea or a bad idea, or how we could measure its results or what. =)

Is my data correct? maatuska and moria being that close together is suspicious.
moria was completely missing, heh. Unfortunately trying to grapha ll the data now gives me an out of memory error!
Here is a graph showing maatuska<->maatuska2 and maatuska<->moria. They agree quite closely, much more than any other two bwauths, but not identically.

It appears there's a single vote file in there that has incorrect data and is throwing the scale off, but a) I like a larger scale and b) trying to correct it would take me another day before notifying everyone of the mistake.
