Dear list, My Exit: https://atlas.torproject.org/#details/4198BD138E5E11B15B05C826B427148CED7D99... My Consendus Weight dropped to 20 today and i found the following in notices.log: Jun 27 12:03:35.000 [warn] http status 502 ("Bad Gateway") reason unexpected while uploading descriptor to server '154.35.175.225:80'). Jun 27 12:07:35.000 [warn] Received http status code 502 ("Bad Gateway") from server '154.35.175.225:80' while fetching "/tor/server/d/C8B7BA97808F42802FCC2DF231A85ACB5B8D848A.z". I'll try again soon. Any ideas what to do or just sit it out ? -- Sincerely yours / M.f.G. / Sincères salutations Sebastian Urbach --------------------------------------------------------------------------- Those who surrender freedom for security will not have, nor do they deserve, either one. --------------------------------------------------------------------------- Benjamin Franklin (1706-1790)

Looks like the drop in cw coincided with messages like these in the log: Jun 27 04:35:48.000 [warn] Received http status code 502 ("Bad Gateway") from server '154.35.175.225:80' while fetching "/tor/server/d/44C3629D79C5366209DB976F1F1588A39B923123+C4716B2DA2AB2CAC2DA0256CD2484050B75371BF.z". I'll try again soon. <snip> 154.35.175.225 is the authority server faravahar which have had network issues in the past.
TL;DR: Faravahar is down, that's probably what's causing it.
Hi Florentin, Sebastian, Faravahar is down, so we are down to 3 bandwidth authorities, which changes the median bandwidth for some relays. It also means that relays that were only measured by Faravahar will get a bandwidth of 20. (Relays with 1 or 2 measurements will have unstable bandwidths.) You can just wait it out until North America wakes up :-) You can check the measurement details for your relay if you want. There's a wiki page for relay operators with slow relays: https://trac.torproject.org/projects/tor/wiki/doc/MyRelayIsSlow
Faravahar is down, so that might be why its caching proxy is giving this response. https://atlas.torproject.org/#details/CF6D0AAFB385BE71B8E111FC5CFF4B47923733...

Dear list, Well Faravahar is finally back but im still wondering why my System (located in France) is measured by exactly 1 System a few thousand miles away. -- Sincerely yours / M.f.G. / Sincères salutations Sebastian Urbach --------------------------------------------------------------------------- Those who surrender freedom for security will not have, nor do they deserve, either one. --------------------------------------------------------------------------- Benjamin Franklin (1706-1790) Am 27.

Actually, it's measured by three bwauths. You can look it up on https://www.freehaven.net/~arma/moria1-v3-status-votes (Careful, it is a very large file.) In ParEpistemenTaksis's case, it has bwauth measurements from moria1, longclaw, and Faravahar. It looks like teor's thought that at least one bwauth is sufficient to get moved off of consensus weight 20 wasn't right. You need three: https://gitweb.torproject.org/tor.git/tree/src/or/dirvote.c?id=tor-0.3.0.8#n... Which on further thought makes sense -- if only rogue dir auth could by itself declare that all its friends in the unmeasured relays set are actually consensus weight 1e9, that wouldn't be cool. So then your question would be "ok, there are four bwauths, how come gabelmoo hasn't measured me?" https://consensus-health.torproject.org/#bwauthstatus And that is a fine question, but I fear the answer is the same as all the other "why is the torflow stuff broken" questions. Tom Ritter has been looking lately at making it better, at least. (Thanks for running an exit relay! :) --Roger
