Time: 2023-06-05 07:35:51.034543026 +0000 UTC Summary: Too many bridgestrap failures Description: The percent of functional bridges is 49.2%.
Something is failing on bridgestrap, It has a constant ratio of 45.5% failing bridges since some hours. I'm investigating.
It has recovered itself after 19h of half of the bridges failing. I didn't see any errors on the logs. Not sure what has happen, maybe a network issue.
toralf asks on #tor-relays about a drop in number of lines in the assignments pool file, and a corresponding spike in the number of his bridges that are listed as distribution strategy 'None' in onionoo.
"there 1234 lines in 2023-06-05-11-14-55 but 1922 in 2023-06-04-15-44-55"
It seems from the timing like it might be related.
In terms of causation, the theory might be "somehow bridgestrap marked a bunch of bridges as down, and then rdsys stopped putting the down bridges into the assignments file"?
But apparently the bridges still have the Running flag on relay-search and onionoo, perhaps because that's different from rdsys's notion of whether bridgestrap said to give it out or not?
