In the past few months of bridge user graphs, there is an apparent negative correlation between obfs3 users and vanilla users: when one goes up, the other goes down. If you draw a horizontal line at about 5500, they are almost mirror images of each other. I don't see it with any other transport pairs. Any idea why it might be?
Hi David, I briefly looked at the raw data behind this graph, but didn't find any obvious problems with the algorithm. I'm running out of time now, but I can share some preliminary results in case you want to dig deeper: - https://people.torproject.org/~karsten/volatile/bridge-users-obfs3-or-mean.p... is the graph that you posted with a third line for mean values. - https://people.torproject.org/~karsten/volatile/bridge-responses.csv.xz contains numbers of responses (for requested consensuses) by bridge, transport, and time interval. - https://people.torproject.org/~karsten/volatile/bridge-responses-by-transpor... shows responses by transport. - https://people.torproject.org/~karsten/volatile/bridge-responses-over-time.p... shows only <OR> and obfs3 responses over time. - https://people.torproject.org/~karsten/volatile/bridge-responses-or-by-finge... shows only <OR> responses higher than 1000 by fingerprint. - https://onionoo.torproject.org/details?fingerprint=231E2DE81DC4314F2035D2C0D... is the bridge reporting those high numbers for <OR> responses. Is PacificSunset maybe one of the bundled bridges? That's all. Maybe it helps? All the best, Karsten
