User Support Report for July 2026
by ebanam 06 Aug '26

06 Aug '26

Hello everyone, This is the report from the user support team for the month of July 2026. Note: (↑), (↓) and (-) are indicating if the number of tickets we received for these topics have been increasing, decreasing or have been the same from the previous month respectively. - Summary of updates from user support - General user support - Farsi-speaking user support - Russian-speaking user support - Frontdesk (email user support channel) - Telegram, WhatsApp and Signal user support channels - Highlights from the Tor Forum - Highlights from Google Play Store # Summary of updates from user support ## General user support * 358 tickets in total (↓1) * 245 tickets on Email * 106 tickets on Telegram * 7 tickets on Signal * Our WhatsApp support channel was unreachable for sometime at the end of July. The issue has been resolved now and the WhatsApp support channel is fully functional as of now. If you reached out to us via WhatsApp in the meantime, your tickets have been processed by the team. But in case you haven't received a message please do not hesitate to reach out again. Apologies for the inconvenience. * Added documentation to explain why Tor VPN will not work if the [Private DNS][] option is set on Android's Network and internet settings. * In light of the [tor 0.4.8 deprecation][] that is scheduled for September, we received a few queries about it. Whenever noticeable, we have been actively encouraging users to update their tor version. * Tails user support parity: the team has been looking at Tails user support parity issue. In this initial phase, the Tor user support team got access to Tails mailbox and learned their ticket triage workflow. We did a [short summary of their tickets]. * In July, dir auths dropped support for [Tor 0.4.6 and 0.4.7-before-0.4.7.120.4.6.x], we had a few users reaching out to us asking why their Tor didn't connect. * We have received a [report] that Orbot for Android is no longer available from the Google Play Store in India. [Private DNS]: https://gitlab.torproject.org/tpo/applications/vpn/-/issues/147 [tor 0.4.8 deprecation]: https://blog.torproject.org/sunsetting-tor-048/ [short summary of their tickets]: https://gitlab.tails.boum.org/tails/tails/-/work_items/20773#note_288224 [Tor 0.4.6 and 0.4.7-before-0.4.7.120.4.6.x]: https://gitlab.torproject.org/tpo/network-health/team/-/work_items/460#note… [report]: https://forum.torproject.org/t/orbot-for-android-is-no-longer-available-fro… ## Farsi-speaking user support * 26 tickets in total (↓41) * 4 tickets on Email * 22 tickets on Telegram * We received several tickets from users in Iran reporting that Google's "My Location" feature showed their location as "Tehran" while using Tor Browser. After investigating, we found that this was caused by Google's geolocation service flagging some Tor exit nodes in Europe as being from Tehran. Our team was able to reproduce the same behavior using Tor Browser, confirming that the issue is not specific to Iranian users. Checking with other geolocation checking services, did not exhibit the same behavior and as expected reflected the location of the Tor exit. * Although the number of support tickets from Iran dropped in July, as per Tor Metrics, [Tor usage in Iran remains stable][]. Iran also remains one of the [top countries by bridge usage]. [Tor usage in Iran remains stable]: https://metrics.torproject.org/userstats-bridge-country.html?start=2026-05-… [top countries by bridge usage]: https://metrics.torproject.org/userstats-bridge-table.html?start=2026-05-08… ## Russian-speaking user support * 442 tickets in total (↓56) * 156 tickets on Email (↓35) * 283 tickets on Telegram (↓22) * 3 tickets on Signal (↑2) * Direct connections to Tor have been gradually blocked in [Belarus][] for a while, and now it is almost completely blocked. Users from Belarus need to use bridges to connect to Tor.

# Roll call: who's there and emergencies We have a few outstanding issues we're keeping an eye on: - gitlab artifacts partition filling up by lelutin - gitlab CI issues monitored by lavamind - jenkins runners migration to new servers by zen and groente # Express check-in We did our usual quick check-in for blocked tasks and how everyone is doing. # Roadmap discussion anarcat brought back a discussion about priorities and roadmap. As a reminder, we establish [yearly roadmaps][] and we have an active [2026 roadmap][] although many things came up that made it hard to follow. [2026 roadmap]: https://gitlab.torproject.org/groups/tpo/tpa/-/work_items/2 [yearly roadmaps]: https://gitlab.torproject.org/tpo/tpa/team/-/wikis/roadmap The goal of the conversation is to see what we'll work on until the end of the year and get a glimpse of priorities for 2027. This was previously [discussed in March][], at our last formal meeting. [discussed in March]: https://gitlab.torproject.org/tpo/tpa/team/-/wikis/meeting/2026-03-10 We also discussed this informally during a check-in in June, where we wanted to do: - groente: mail *and* idm - lavamind: download and support sites in 2026, and openvox (2027?) - zen: prometheus / puppet 2026, firewall / backups 2027? - anarcat: matrix and websites merge - gab: minio Here are per-person priorities. ## lavamind - yec coming quickly, hoping for another push on donate-neo: tech debt to catchup, rate limiting improvements, before october 2026 - some website migrations to marble in 2026? need to check with the web team - would love to move GitLab artifacts to object storage ## lelutin - minio retirement in 2026 - joining zen in the puppet / tails merge for 2027 ## anarcat - matrix process in 2027 - we should prioritize prometheus, firewall and backups in 2026/2027 - websites merge seems to be a priority for the tails team ## groente - AI / security pre-emption? better incident response? - LDAP cleanup in 2026? - start of an idm in 2027? hard to predict, collaboration is slow - email not blocked on IDM - documents is much harder ## zen - tails merge roadmap need a review. things came up (e.g. migrating the whole jenkins setup, twice) and we didn't know how much time we could free up to work on the merge, so we have delays - priorities are finishing prometheus and puppet in 2026 - 2027: firewall is a huge rework and backups are important # Next meeting Next month, we hope to resume our monthly cadence. # Metrics of the month * host count: 142, LDAP 141 (!), Puppet 141 (!) * number of Apache servers monitored: 33, hits per second: 625 * number of self-hosted nameservers: 6, mail servers: 12 * pending upgrades: 1, reboots: 98 * average load: 1.78, memory available: 4.4 TB/8.4 TB, running processes: 300 * disk free/total: 111.7 TB/254.4 TB * bytes sent: 533.6 MB/s, received: 348.2 MB/s * [GitLab tickets][]: 286 tickets including... * Needs Triage: 1 * Not Scheduled: 178 * Backlog: 73 * Next: 21 * Doing: 13 * (closed: 4614) * [~Needs Information][]: 5 open, 137 closed * [~Needs Review][]: 6 open, 213 closed * [~Technical Debt][]: 11 open, 39 closed [Gitlab tickets]: https://gitlab.torproject.org/tpo/tpa/team/-/boards [~Needs Information]: https://gitlab.torproject.org/groups/tpo/tpa/-/issues/?state=opened&label_n… [~Needs Review]: https://gitlab.torproject.org/groups/tpo/tpa/-/issues/?state=opened&label_n… [~Technical Debt]: https://gitlab.torproject.org/groups/tpo/tpa/-/issues/?state=opened&label_n… We have completed all major Debian upgrades and are not currently tracking upgrades, at last! -- Antoine Beaupré torproject.org system administration

Smart Options for Students Facing Academic Pressure
by jollylara39＠gmail.com 04 Aug '26

04 Aug '26

Academic pressure seems to be a really common challenge for a lot of students, especially those trying to juggle college, work responsibilities, and personal needs all at once. When tight deadlines, several assignments, midterms, and even online classes stack up at the same time, it can feel like everything is due immediately, and honestly that can get overwhelming fast. I think the first step is, well improving time management, like making a study routine that actually feels realistic , and turning big tasks into smaller milestones. Also, reaching out to professors, being part of a study group, or even getting tutoring support can really shift things when a topic feels unusually hard, or just not clicking. Some students then consider more formal academic support and search for help such as “pay someone to do my online class” when they feel they just can’t keep pace with the workload. But it’s still important that every student really understands their school’s academic integrity rules, and chooses guidance that fits those standards. Otherwise it can turn into problems later, even if the short term pressure feels impossible. If you’re looking into what academic support services are available, you can find more information by going to https://myassignmenthelp.com/take-my-online-class.html. Of course, everyone experiences academic pressure in their own way, so there isn’t a single method that fixes it for everyone. What strategies have helped you stay on track with your workload? And have you ever ended up in a situation where deadlines piled up, if so what ended up being the most effective way you handled it?

Are there some obvious grouping strategies that we can already consider? e.g., by PT, by bandwidth (lower bandwidth bridges sacrificed to open-invitation buckets?), by locale (to be matched with a requesting user's geoip or something?) 2. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges (and untrusted users have access to 1)? More? Less? theodorsm: 2026-05-28 Last weeks: - Researching possible DTLS block in Russia - https://github.com/net4people/bbs/issues/603#issuecomment-4451730751 - Implementing DTLS 1.3 in pion Next weeks: - Implementing DTLS 1.3 in pion Help with: - Facilitator Queue: cohosh meskio onyinyang shelikhoo 1.
