Graphs of Snowflake bridge bandwidth since March 2024 domain fronting changes
by David Fifield 15 Mar '24

15 Mar '24

Here are some graphs of the bandwidth at the 2 Snowflake bridges since the end of domain fronting on Fastly on 2024-03-01 (https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/135) You can compare this to similar analysis made in October 2023, after a similar situation when the default front domain changed from Fastly to Cloudflare: https://lists.torproject.org/pipermail/anti-censorship-team/2023-October/00… 1. As before, snowflake-02 was relatively harder hit than snowflake-01. But this time it didn't get nearly as close to zero. However, there's an evident secondary step down on 2024-03-07, which may or may not be related. 2. Also as before, snowflake-02 suddenly (within 10 minutes) recovered a large amount of bandwidth about 14 days later, at 2024-03-15 10:45. A similar sudden increase is visible with snowflake-01 at the same time. Last October, it (if it is indeed the same effect) happened at about 11:45, one hour later UTC.

Snowflake and Fastly
by Michael Rogers 04 Mar '24

Hi all, While updating Briar's bridge config I noticed that Moat is still returning a Fastly URL among its snowflake bridge lines for some countries. Are these lines still working (temporarily?) or should I substitute the CDN77 front? Thanks, Michael
