Hi Mike, What you said is very interesting, it was the missing part for me to understand why the weight of the relay in the consensus can drop (or rise again) so quickly (sometimes 3 times per day) without being caused by any change of used bandwith on the network cable of the dedicated machine

Hi Mateusz, If there wasn't any network connection then the script would not give the right traceroutes even though the script will still run (with empty traceroute results). So if it is not too much of a trouble please restart the script and please make sure that the network is ac

Also keep in mind that what the bandwidth authorities actually measure is not total capacity but spare stream capacity (by downloading large files through at least 5 different two hop circuits times for each relay). They then use this stream throughput measurement to create a multiplier to multiply

Dear list members, We have seen a small amount of odd entries like "slash24-proxy" in the "phases completed" column at the scoreboard: http://128.174.241.211:443/relay_scoreboard It was a small script bug and Anupam is going to fix it today. No data is lost, please check back with the scoreb

Hi Karsten, and thank you very much for your answer. Few days ago I have re-started my 2 tor daemons (same identity, ArachnideFR94 and ArachnideFR94v2) on same the server on which I had these huge falling down/rising up/fall down again consensus weight problems. They started back from nearly 0

Hi starlight, hi Julien, the bandwidth scanner system is quite complex, so it might be the case that part of it is broken. But from this thread that's hard to say, and it's impossible to know what part needs fixing. Want to help us debug the problem(s) you observed? Here are a few possible star
