Mac app / Safari extension for Snowflake

Browsing through some search results, I found: https://apps.apple.com/us/app/torproject-snowflake/id1597501940 (https://web.archive.org/web/20220222083316/https://apps.apple.com/us/app/to…) https://github.com/jayluxferro/snowflake It looks like a repackaging of the Snowflake JavaScript proxy code for Mac and Safari environments. Maybe we could get in touch with the developer and find a way to adopt it into the main repository?

It looks like Azure is going to shutdown domain fronting: https://www.microsoft.com/security/blog/2021/03/26/securing-our-approach-to… There isn't a time frame listed in the article, and I haven't gotten any notifications through my Azure account yet. Cecylia

Graphs of Snowflake bridge bandwidth since March 2024 domain fronting changes
by David Fifield 16 Mar '24

16 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 05 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
