Some learning points and conclusions for our AMA
by Nothing to hide 21 Jun '25

21 Jun '25

Hi fellow operators, The first Ask Me Anything by Tor operators was held on 13-06-2025. The result can be viewed here: https://www.reddit.com/r/TOR/comments/1la9zgw/tor_operators_ask_me_anything/. We also made a quick evaluation for learning and improving the format going forward. This (and other AMA stuff) can be viewed here: https://codeberg.org/nothingtohide/TorAma/src/branch/main/250613-AMA-1/eval…. If you have any questions or suggestions, feel free to reach out. Have a great day, Nothing to hide

Attempting to create a relay with Orbot
by blueapple128 20 Jun '25

20 Jun '25

Hi, I am trying to use Orbot's "Enable your device to be a non-exit relay" option, but (after waiting enough hours) the relay's nickname fails to show up in Tor Metrics' Relay Search. How can I begin to debug this?

Tor Operators Ask Me Anything - 13-06-2025
by Nothing to hide 13 Jun '25

13 Jun '25

Hi Tor operators, We already briefly mentioned an upcoming Ask Me Anything (AMA) by Tor operators during the Tor Operator Meetup on the 10th of May. And now it's time for the announcement: https://www.reddit.com/r/TOR/comments/1krv4rt/tor_operators_ask_me_anything…. During this AMA, anyone can engage with us directly and ask us anything they're curious about. The following Tor operators are participating: R0cket, Nothing to hide, Artikel10 and CCC Stuttgart. The Ask Me Anything will be held on Friday 13 June 2025 between 08:00-23:00 UTC on /r/TOR. Feel free to ask your questions the 13th or to share this AMA with people or your communities. We also have a post on Mastodon to share: https://mastodon.social/@tor_ama/114545560947637613. We're experimenting with this format to see whether it benefits the community. Our goal is to provide answers and context about Tor, dispel myths and inspire more people to become Tor operators--or encourage current operators to expand their efforts, perhaps by scaling up or running exit relays. This initial AMA will help us learn from our mistakes and if successful, establish a regular series where other operators (of all shapes and sizes) can participate. We're looking forward to the 13th of June! And if anyone has questions about the AMA, feel free to ask them or send people our way :). Have a great day, Nothing to hide

Observing Moria1’s Higher Missing-Relay Measured Rate (May 24–30 2025)
by Tor at 1AEO 04 Jun '25

04 Jun '25

Been exploring how each directory authority measures relays and noticed that, over the week of May 24–30, Moria1 consistently reports significantly fewer relays measured than its peers—about 6% missing versus ~3.5% for most other authorities (over 2 σ below the mean). Quick stats (May 24–30): - Moria1: Weekly missing avg = 556 relays, Z-score = 2.44 - All authorities: Mean missing = 314 relays, σ = 99 Attached the full spreadsheet, some tables, and charts below. Has anyone else spotted this pattern or have ideas why Moria1’s “number of relays voted about” is lower? Any insights or pointers would be greatly appreciated!

Navigating Top Relay Trackers: Measure and Compare Tor Nodes

Tor Relay Deployment Dilemma: When to Not Pay for Underutilized Server Resources?
by Tor at 1AEO 23 May '25

23 May '25

Part 3 - Looking for feedback on our Tor relay configuration decision: Looking for guidance on optimizing server / bandwidth spending for Tor guard / middle relays across datacenters. Our current setup: - All same cost: Three servers in different datacenters, each with 10 Gbps unmetered bandwidth. - Identical hardware/software: Each server has 128 threads, 512GB–768GB RAM, and the same software stack. - Diversity benefits: Each server hosts fewer than 10 other relays, enhancing overall network diversity. - Primary differences: Geographic location and upstream peering/routing. Current Utilization: - Server 1: 2Gbps utilized (20% utilization) - Server 2: 6Gbps utilized (60% utilization) - Server 3: 8Gbps utilized (80% utilization) Overall, using 16 Gbps out of 30 Gbps purchased -- roughly half our bandwidth is idle / "wasted". Assuming we can't significantly optimize these servers any further and given the significant under utilization on Server 1 (80% idle) and Server 2 (40% idle), what would you do in this scenario? Some options we’re considering: - Consolidation: Paying only for the servers with the highest utilization. - Repurposing: Allocating the idle bandwidth to another purpose that benefits Tor (or a similar effort). - Reinvestment: Using the funds from Servers 1 and 2 to acquire additional high-utilization capacity (e.g., more of Server 3 configuration) to boost our overall contribution closer to 24 Gbps. - Other strategies: Any alternative approaches you might suggest. Appreciate any thoughts or best practices to help reduce wasted expenditure while maximizing the utility of our available resources. Thanks for your insights!

Seeking Advice on Running a Tor Exit Node in India
by RUSTEDUSTED 19 May '25

19 May '25

Dear Tor Operators, I hope this message finds you well. I am planning to set up a Tor exit node and would like to seek your valuable advice and guidance before proceeding. Specifically, I want to understand the following: - What are the essential technical and operational considerations I should be aware of before running an exit node? - Are there best practices or configurations you recommend to ensure the node runs securely and efficiently? - What kind of bandwidth allocation is ideal? I am considering allocating around 30-40 Mbps on my internet connection—would this be sufficient or optimal? - Could you please share insights on the legal responsibilities and potential risks involved with operating a Tor exit node in India? - Are there any specific resources, communities, or contacts you recommend I engage with for ongoing support? - (most importantly) what hardware accelerations should my device support?? is it fine if i run it on raspberry pi 5 or would it need a modern x86 CPU? I appreciate any advice or resources you can share. I am eager to contribute responsibly and effectively to the Tor network. Thank you very much for your time and help. Best regards, Pradnyesh Email: rustedusted(a)proton.me Location: Pune, India

Patela: A basement full of amnesic servers
by Osservatorio Nessuno 07 May '25

07 May '25

Hi everyone! A while back, we announced[1] our project to set up a server facility in Italy to host Tor exit nodes. After several weeks of testing, we’re excited to share that our first nodes are now in production, running on our autonomous system. [2] Four of these nodes operate diskless thanks to System Transparency [3] and Patela [4], a small, pull-based tool we developed to configure exit nodes efficiently. To optimize this infrastructure, we’ve worked on multiple fronts, including mTLS for nodes authentication, TPM for crypto operation and nftables rules. In this post[5], we’ll explain how the system works, and we’d love to hear your thoughts and feedback via the mailing list. Now that we’ve completed this initial testing phase, our next goal is to acquire suitable hardware to increase bandwidth capacity. Stay tuned for updates!
