Clément Février:
Hello,
On April 5th, the consensus weight of my tor relay dropped to 0, see https://metrics.torproject.org/rs.html#details/33D88F331408141F2A2CC563239E5...
As far as I know, nothing specific happened, no update nor reboot. Nothing in the logs. Can anyone explain me what happened?
I think your relay got hit by one of the critical bugs in our sbws (simple bandwidth scanner). We had some outage of Torflow bandwidth scanners so that sbws ones got the majority when voting. We saw bugs like #33775[1] as a result which affected a number of relays.
Looking at the current results for your relay it seems things getting back to the previous state. That's due to some directory authority operators either switching away from sbws to Torflow again or getting Torflow going on their machines (again). (see Roger's mail yesterday[2] for the different options we had in mind and my mail[3] today for the state of sbws and our next steps in that area for more context)
Sorry for the inconvenience but things should go back to a normal level rather soon,
Georg
