Hi Michael,

The Briar team's nightly tests of our bridge config have shown that some of the default obfs4 bridges listed in the Tor expert bundle's pt_config.json have been down for some time:

192.95.36.142:443 193.11.166.194:27015 193.11.166.194:27020 193.11.166.194:27025 209.148.46.65:443 45.145.95.6:27015

Of these, 193.11.166.194 immediately rejects connection attempts on the listed ports, while connection attempts to 192.95.36.142:443 time out. The other two accept TCP connections but are very slow, so Tor can't bootstrap through them in a reasonable amount of time.

Is this a known issue, and is it expected to be temporary, or should we exclude these bridges from our config? Is been a while that some builtin bridges are failing, we've been tracking it on this issue: https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/141

But I've been neglecting acting on it. I'll look into this on the comming weeks and update the pt_config.json file.

BTW you can update those bridges from the moat api, and I'm thinking on making it so there only lists the ones that are functional: https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/blob/main/doc/moat...

Thanks for having a look to this.

Hi all, I run the bridge at 209.148.46.65:443 and I'm not aware of it being down.  It's been doing the same thing for months/years (bandwidth data below). If there's a problem with it, if someone could reach out to me and let me know what's up, that would be helpful.
