Time: 2023-02-22 00:47:51.034543026 +0000 UTC Summary: Too many bridgestrap failures Description: The percent of functional bridges is 43.0%.
I'm investigating this. It looks like if bridgestrap tests few bridges it's ratio of functional bridges is pretty high, but when it tests 25 bridges (the most common requests from rdsys) it has a 20-30% of functional bridges. I hope we don't have a regression back to: https://gitlab.torproject.org/tpo/anti-censorship/bridgestrap/-/issues/7
bridgestrap is currently using the tor binary installed in polyanthum, that is 0.4.7.13 which should have a fix for this issue.
