major outage at Hetzner
by Antoine Beaupré 04 Feb '23

04 Feb '23

Hi, We are witnessing a large outage at our main service provider, Hetzner. According to the information we have gathered so far, four switches (4!) have failed and that affects four (yes, again, 4!) of the servers in the 8-node cluster. Many services are down. We have not made a full inventory yet, but the mail server is currently up so I'm using this time to send this notification while we decide on short-term mitigations. We hope this outage to be resolved shortly, but we do not have an ETA. Stay tuned. a. PS: and yes, that affects the mechanics behind status.torproject.org so we don't have an update on that site just yet. We have a backup plan for that, but we never drilled for it, so it could take a while to setup. -- Antoine Beaupré torproject.org system administration

Joydeep's Monthly Status Report for January 2023
by Joydeep Sen Gupta 03 Feb '23

03 Feb '23

Hello everyone! Here are my updates from January 2023. In total, I resolved 1275 tickets across our email, telegram and signal user support channels. Most of my work last month has been around helping users in regions where Tor is censored. There has been another massive uptick in user requests from China. I have been working with users to get feedback, help them use pluggable transports and troubleshoot Tor. On Tor Browser front, we had one major stable release and with that some post-release user support work. I received a few reports of users on Apple Silicon-based Macs unable to fetch Tor Browser updates[1] since Tor Browser 12. The issue is resolved in the latest update i.e. 12.0.2. I also made a small update to the documentation about our GetTor distributor in the Tor Browser Manual[2]. Now, a quick overview of our user support channels: Timeline: 01 - 31 January 2023 # Frontdesk tickets created: 816 tickets resolved: 1461 Most frequent tickets by numbers: 1. 308 RT Tickets - Private Bridge requests from China 2. 96 RT Tickets - How to use a Tor Bridge in Russia 3. 59 RT Tickets - Circumventing censorship with Tor in Iran 4. 9 RT Tickets - Unable to update to 12.0.1 on Apple Silicon-based Mac[1] # Telegram and Signal Support channel (cdr.link) tickets resolved: 650 The most frequent tickets we received have been about: 1. 195 tickets: Circumventing censorship in Russia 2. 166 tickets: Circumventing censorship in Iran 3. 92 tickets: Circumventing censorship in Turkmenistan 4. 19 tickets - Circumventing censorship in China # Tor Forum Most popular topics in the Support category (in terms of number of views): 1. "Changing operating system changes browser fingerprints?" [3] 2. "Wanted to run something like tor network in china"[4] 3. "Road from restricted to unrestircted!"[5] 4. "Do Snowflake Proxies Reveal Tor Traffic to ISP?"[6] 5. "Snowflake standalone proxy in Docker: How to make NAT unrestricted?"[7] Thanks, -- Joydeep [1]: https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/4… [2]: https://gitlab.torproject.org/tpo/web/manual/-/issues/138 [3]: https://forum.torproject.net/t/changing-operating-system-changes-browser-fi… [4]: https://forum.torproject.net/t/wanted-to-run-something-like-tor-network-in-… [5]: https://forum.torproject.net/t/road-from-restricted-to-unrestircted/6409/ [6]: https://forum.torproject.net/t/do-snowflake-proxies-reveal-tor-traffic-to-i… [7]: https://forum.torproject.net/t/snowflake-standalone-proxy-in-docker-how-to-…

Nina’s Monthly status report for January’23
by Nina 03 Feb '23

03 Feb '23

Hi! This is my report for January, 2023. In that month, I resolved 770 tickets: On Telegram (@TorProjectSupportBot) - 464 On RT (frontdesk@tpo) - 306 On January'23, I worked on user support, mostly but not exclusively focusing on Russian-speaking users. The main directions of my communication with users were: - Sharing bridges and troubleshooting around bridges; - Gathering user feedback regarding the new TB versions 12.0.1 and 12.0.2; - Finding the working ways of censorship circumvention and getting feedback on working and not working solutions. @raya and I also started to work on the educational campaign to expand the understanding of the Tor Browser features and use it for censorship circumvention and avoidance of surveillance. In January, I got several complaints from OPPO/Realme phone users [1] with a "Proxy Server Refused Connection" error. I've spotted a Mac-related bug [2], which fortunately does not persist after 12.0.2 release.

Anti-censorship team meeting notes, 2023-02-02
by meskio 02 Feb '23

02 Feb '23

Hey everyone! Here are our meeting logs: http://meetbot.debian.net/tor-meeting/2023/tor-meeting.2023-02-02-15.58.html And our meeting pad: Anti-censorship team meeting pad -------------------------------- Next meeting: Thursday, February 9 16:00 UTC Weekly meetings, every Thursday at 16:00 UTC, in #tor-meeting at OFTC (channel is logged while meetings are in progress) == Goal of this meeting == Weekly check-in about the status of anti-censorship work at Tor. Coordinate collaboration between people/teams on anti-censorship at the Tor Project and Tor community. == Links to Useful documents == * Our anti-censorship roadmap: * Roadmap: https://gitlab.torproject.org/groups/tpo/anti-censorship/-/boards * The anti-censorship team's wiki page: * https://gitlab.torproject.org/tpo/anti-censorship/team/-/wikis/home * Past meeting notes can be found at: * https://lists.torproject.org/pipermail/tor-project/ * Tickets that need reviews: from sponsors, we are working on: * All needs review tickets: * https://gitlab.torproject.org/groups/tpo/anti-censorship/-/merge_requests?s… * Sponsor 28 * must-do tickets: https://gitlab.torproject.org/groups/tpo/-/milestones/10 * possible tickets: https://gitlab.torproject.org/groups/tpo/-/issues?scope=all&utf8=%E2%9C%93&… * Sponsor 96 * https://gitlab.torproject.org/groups/tpo/-/milestones/24 * Sponsor 139 <-- hackerncoder, irl, joydeep, meskio, emmapeel working on it * https://pad.riseup.net/p/sponsor139-meeting-pad == Announcements == * == Discussion == * is there any proposal to encode bridges into human-memorable form? like a list of words? * people have trouble pasting in the bridge lines (fail to get the entire line for example), and support wants either: * something that is easier to copy and paste, or * and easy way to verify that the line was pasted correctly (visual checksum or similar) * bridgemoji are meant to serve this role * gus will open an issue for user research of different options (QR code, sequence of words, others) * snowflake fallback from domain fronting to amp cache, how/whether/when/etc to implement (https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow…) * arma is going to check how hard would be to change c-tor to only connect to two bridges instead of all of them at once. So maybe we can duplicate bridges with domain fronting and amp cache. There is a patch which implements this idea: https://gitlab.torproject.org/tpo/core/tor/-/issues/40578 But see also the caveats on https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * we need to check the consecquences of using amp cache, and if we are ok having half of our users using it * Three possible options: * multiple bridge lines with different configurations, having multiple bridges with different fingerprint or fixing tor to allow multipe bridgelines with one fingerprint * different definitions in TB for domain-front and amp-cache so users can pick * snowflake client does control the fallback, maybe by passing flags with what to fall back to * use ampcache for snowflake in IR? * https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/115 * https://gitlab.torproject.org/tpo/anti-censorship/rdsys-admin/-/merge_reque… * our domain front for both snowflake and circumvention settings was blocked in Iran for 9 days * Packet loss resulted in performance issue for snowflake in China * https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * snowflake fails to bootstrap in the vantage point due to packet lost * shellikhoo is investigating it * (from ahf): do we have an idea about how many C tor modifications that needs to be reviewed before s28 is wrapped up? Purely so we can plan this for take-in. for next week: * Conjure is in nightly versions of Tor Browser now, an update on how it's going and the roll out plan == Actions == * We should make a ticket for pion to cache its stun answers when possible, because right now it surprises us by asking way more stun questions than it actually needs to. * We might want to be able to spin up our own stun servers, on our own ip/port, for debugging. We should talk to TPA about that goal at some point (not urgent). * Roger will look more at https://gitlab.torproject.org/tpo/core/tor/-/issues/40578 ("only contact the first few working bridges on your bridge list") and plan to have a sense of whether it will be an easy hack or a hard one, for next week. == Interesting links == * https://en.wikipedia.org/wiki/Snowflake_(software) == Reading group == * We will discuss "" on * * Questions to ask and goals to have: * What aspects of the paper are questionable? * Are there immediate actions we can take based on this work? * Are there long-term actions we can take based on this work? * Is there future work that we want to call out in hopes that others will pick it up? == Updates == Name: This week: - What you worked on this week.

PieroV's Monthly Status Report, January 2023
by Pier Angelo Vendrame 01 Feb '23

01 Feb '23

Hi everyone! Here is my status report for January 2023. This month I worked on several small tasks to polish many small details, especially on the tor-browser-build repository. For example, I removed a shim used to launch tor on Tor Browser for macOS. It was used to declare some Python 2.x compatibility variables for obfs3, so it has not been needed for a long time [0]. Another macOS task was switching our DMG installers from ISO images to HFS filesystems to show a custom volume image [1]. This was quite involved because it introduced reproducibility issues, for which I had to patch the HFS creation to use a deterministic volume UUID [2]. All were part of a parent ticket about cleaning up the "Bundle-Data" directory of Tor Browser [3]. In a somehow related topic, I reviewed how we ship extensions [4]. Moving them to the distribution directory might allow us to enable some profile repair tools if needed, or multiple profiles. On the Tor Browser side, I fixed a problem when running the browser for a long time [5]. I did not handle stdout correctly when switching from nsIProcess to Subprocess. Shoutout to the members of our community for finding the cause, and apologies for any inconvenience it caused! Then, I investigated and tried to remove some calls to home that we inherited from Firefox [6]. Finally, I went back to improving our portable profile directory patch. I feel we are reaching its final form. Best, Pier [0] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/41569 [1] https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/2… [2] https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/4… [3] https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/4… [4] https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/4… [5] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/41549 [6] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/40788
