Exit Relay DNS Health Module for Exitmap - Seeking Guidance Before Deployment
by Tor at 1AEO 26 Jan '26

26 Jan '26

Hi Network Health Team, A few large-scale exit relay operators have asked for better visibility into DNS health across their relays. We've built an exitmap module, dnshealth, to address this and want your input before we start running scans and publishing results. What It Does - Generates unique DNS queries per relay (wildcard subdomain → expected IP) to avoid caches - Classifies failures: timeout, NXDOMAIN, wrong IP, SOCKS errors - Outputs structured JSON with latency and error details All code is open source: https://github.com/1aeo/exitmap Initial testing: ~98% success rate across ~3k exits, 50-90 true failures per scan, 4-8 min runtime. Before We Proceed 1. Any concerns with us running regular scans and publishing results? 2. Recommendations on scan frequency or methodology? Happy to adjust our approach based on your guidance.

Hey there, https://metrics.torproject.org/userstats-censorship-events.html shows a "500 Internal Server Error". Home->Users->Top-10 countries by possible censorship events Not sure since when, but it's been like that for at least 24h. Kind regards and thanks for your work, everyone! Dutt

on blacklist

Hello I was surprised to find that I was blacklisted on some sites. I found a long blacklist on GitHub, including my Tor relay's IP address. I've now disabled the relay, of course. Too bad. hallogen https://github.com/firehol/blocklist-ipsets/blob/master/et_tor.ipset

500 Internal Error - Top-10 countries by possible censorship events
by Culda, Alexandru 09 Jan '26

Hi there, My name is Alexandru Culda and I am a Master’s students in the Netherlands studying InfoSec. I am tasked with doing a literature review on how China’s blocking TOR and its countermeasures to circumvent the censorship. I was interested in this specific metric: Top-10 countries by possible censorship events (https://metrics.torproject.org/userstats-censorship-events.html) but it seems I get a 500 Internal Server Error. It would be tremendously helpful to get access to this list for research purposes. Its provision would be deeply appreciated, both by me and my professor. If needed, I can provide more information about the scope of the research. Deeply appreciating your time and consideration whilst hoping I could get access to this, Alexandru Culda

Hyperlinks Not Forwarding to Correct URL's

https://bridges.torproject.org/info#reserved The URL's for bridge distribution mechanism(s) are not functioning anymore on metrics.torproject.org on relay pages. When I go to a relay on metrics.torproject.org and click on "Reserved" as shown in the screenshot, it no longer forwards to correct place. https://metrics.torproject.org/rs.html#details/19C9B070003C9670BB6B5693771F… Under "Bridge Distribution Mechanism" Click Reserved https://bridges.torproject.org/info#reserved And instead it forwards to this URL which does not have the relevant information. https://support.torproject.org/tor-browser/circumvention/#reserved [image.png] I found this documentation here: https://support.torproject.org/relays/running/bridge-distribution-method/ Which references this link that has the actual information: https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/blob/main/doc/dis… I was wondering if these hyperlinks could be updated on metrics.torproject.org to go to the correct URL mentioned previously (e.g. for reserved): https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/blob/main/doc/dis… Thanks and appreciate the project, - Andrew Pelletier
