Spike in client polls from Snowflake broker metrics
by Cecylia Bocovich 07 Sep '23

07 Sep '23

I was alerted by trinity-1686a on irc that Snowflake standalone proxy operators were reporting on #tor-relays about increased OOM errors from increased load as of 2023-08-28. After looking at the Snowfake broker metrics[0], there's a huge jump in client polls (seen by summing the client-denied-count and client-snowflake-match-count). I've attached a graph of the collected prometheus metrics that shows this spike happening at exactly 17:40 UTC on 2023-08-27. It looks like way too sharp an increase to me to be a censorship event, perhaps it is a DoS? It's still too early to see the bridge metrics from the metrics page, but we should start to see the effects there tomorrow. [0] https://metrics.torproject.org/collector.html#snowflake-stats

Request obfs4
by Ahmet Orakov 15 Aug '23

Hi everyone, I would want to test obfs4 bridges if you have them already properly configured. Please consider sharing bridges with me and I will definitely inform you about the results. We assume that the government of Turkmenistan managed to block all the currently listed obfs4 bridges on the different platforms. Feel free sending me bridges for testing purposes. Best regards, Ahmet
