More resources required for Snowflake bridge
by David Fifield 04 Apr '22

04 Apr '22

It has been great to see all the support and encouragement for people running Snowflake proxies. Thank you! But there is a problem: the Snowflake bridge (which all the temporary proxies forward their traffic to) is going as fast as can on its current hardware. The server is running close to 100% on all CPUs more or less constantly. As more people use Snowflake, they each get a smaller share of the limited available performance. The limited capacity of the bridge is the cause of the [recent slowness of Snowflake](https://www.reddit.com/r/TOR/comments/t49i14)—in the past 2 weeks it's gone [from 12,000 to 16,000 users, without a proportional increase in bandwidth](https://metrics.torproject.org/rs.html#details/5481936581E23D2D1… We've spent significant engineering resources already to make the most of the hardware, such as [load balancing multiple tor instances](https://github.com/net4people/bbs/issues/103) since a few weeks ago. This effort has roughly doubled the available bandwidth of the bridge, but it's still not enough. Demand will only continue to rise. The bridge needs to be moved to faster hardware. Its current hosting is free of charge, but is already on the highest-spec VPS configuration (8 CPUs, 16 GB). Switching to a server with, say, double the CPUs will have an immediate positive effect: the proof of that is that while we were installing the load balancing on the main bridge, I paid for an only slightly higher-spec server to handle Snowflake traffic during the upgrade, and during that week the bandwidth [immediately rose to higher than where it is now](https://github.com/net4people/bbs/issues/103#issuecomment-1033067920). I used Snowflake a lot during that week, and the difference was palpable. The minimum server required has something like 16 CPUs and 32 GB of RAM. meskio found some suitable [dedicated servers for about $200/month](https://lists.torproject.org/pipermail/anti-censorship-team/2022-February/000220.html) with unlimited bandwidth. (I estimate current needs are something like [100 TB/month of bandwidth](https://bugs.torproject.org/tpo/anti-censorship/pluggable-transp…, of course expected to grow.) I'm writing this to make people aware that the current cause of poor Snowflake performance is known: it's limited CPU capacity at the bridge, not general Tor slowness or slowness of the temporary proxies. Solving the problem will cost a few hundred dollars per month, at least for the near future. I am open to suggestions about what to do. I promised myself I would not again get in the situation of paying out of pocket for important infrastructure. I've already contacted the Open Technology Fund about a possible rapid response grant, but have not gotten a response yet. I'm willing to continue administering the bridge, as I do now. * Since 2022-02-03, Tor Metrics graphs for the Snowflake bridge are 1/4 what they should be, until the fix for https://bugs.torproject.org/tpo/network-health/metrics/onionoo/40022 is deployed.

metrics releases
by Silvia/Hiro 01 Apr '22

01 Apr '22

Hi, We have released new versions of collector, onionoo and the metrics website this week. You might have noticed the changes already if you use these systems (changelog below). In collector we stopped sanitizing contact info for bridges (https://gitlab.torproject.org/tpo/network-health/metrics/collector/-/issues…) In onionoo and the website you will notice some bridges might have a new parameter, called blocklist. Some context: bridgedb has a mechanism to not distribute certain bridges in certain country/location. If we find a bridge has been blocked in a country we can use this mechanism to not distribute it in that location. We are now exposing this information in the bridge page on relay-search. The blocklist is also exposed in the bridge-pool-assignments, as: 02l463ff20f55qyddec130419b7t3y98de0f7c18 https transport=obfs4 ip=4 blocklist=ru If some or any of your bridges do not have the blocklist parameter this means your bridge is not being blocked, i.e. is being served to all locations. Related tickets: https://gitlab.torproject.org/tpo/anti-censorship/bridgedb/-/issues/40036 https://gitlab.torproject.org/tpo/network-health/metrics/collector/-/issues… Changelog Collector version 1.18.2 - 2022-03-31 * Medium changes - Stop sanitizing contact info for bridges.

PieroV's Monthly Status Report, March 2022
by Pier Angelo Vendrame 01 Apr '22

01 Apr '22

Hi everyone! Here is my status report for March 2022. This month we released several versions! 11.0.7, 11.0.9, 11.5a6, 11.5a8 for desktop, and now we have just started to prepare 11.0.10. I have helped review the rebases, and I have been the second builder for some of them. Some of the fixes they include are partially my doing 🙂️: * I have fixed a small issue that broke Onion services authentication in 11.0.6 (tor-browser#40802); * I have added a patch to keep the URL fragment/hash on onion-location redirects (tor-browser#34366); * I have completed the patch to show IPv6 addresses in the circuit display that we initially received by @illia-v from our community (tor-browser#14939). For Android, I have tried to help with the crash we have in 11.0.8. But eventually, we started working on the update from Firefox 96 to 99. I have rebased Geckoview (tor-browser#40857), reviewed other rebases, and helped solve some build problems (all the details are on tor-browser-build#40446). Then, I continued with the work from the previous months. I have fixed some small details in the about:torconnect and about:preferences#connection pages. I also presented them at our latest demo day 🥳️. Yesterday I started working on the new UI to show configured bridges, and I will continue it in the first days of April. As anticipated last month, I also continued working on the HTTPS-Everywhere replacement and the TBB tests. In particular, I have added a test to monitor our font fingerprint and make sure it does not change between versions. Thank you all! Cheers, Pier

Updates from the web front
by Jérôme Charaoui 29 Mar '22

29 Mar '22

Hello, Just a quick note for anyone involved/interested in web development stuff at the Tor Project. From now on, all production deployments of web projects under the tpo/web GitLab namespace, in addition to the TPA status site, will need to be triggered manually by project maintainers via the GitLab CI web interface or the API. Before triggering those deployments, we encourage contributors to review their changes on the new staging websites for which deployments are themselves automatic. To access the staging version of a website, simply replace "torproject.org" with "staging.torproject.net" in the URL, so for instance the staging deployment of "www.torproject.org" is accessible at "www.staging.torproject.net", the one for "blog.torproject" is at "blog.staging.torproject.net", and so on. For details, please see the GitLab issue: https://gitlab.torproject.org/tpo/web/team/-/issues/34 In addition, from now on both staging websites and review apps (under review.torproject.net) are concealed with a simple HTTP authentication prompt, to avoid regular visitors and web indexes from accessing them. To dismiss the prompt, simply enter "tor-www" (without quotes) in the username field, leaving the password field blank. Or simply add tor-www to the URL as in: https://tor-www@blog.staging.torproject.net For details about this change, see the GitLab issue: https://gitlab.torproject.org/tpo/web/team/-/issues/35 Thanks, -- Jerome aka lavamind

Hi! The DEMO day for this month will happen on March 23rd at 1600 UTC. I will send the link for the BBB room a few hours before the event. What is a Demo Day? ------------------- An hour long session at Tir Project's all hands meeting where different people present 5 minutes ideas, tools, hacking or anything that they think it may be interesting for the Tor community. Presenters will have 5 to 8 minutes and people can ask questions via text in the pad for 3 minutes. For this month we will have: - Guardian Project: with Orbot for iOS https://orbot.app - Anarcat: Undertime - Dealing with the nightmare of timezone and time changes on the commandline in Python. - Shelikhoo: V2Ray - V2Ray is one of the external proxies one can use to connect to Tor network. It can help user bypass some of the most restrictive censorship here on this planet. Combined with Tor it help user to browse Internet freely, speedy and anonymously. Here is short demo of V2Ray and how to use it to connect to Tor. - Hiro: Metrics Dashboard. - Rhatto: Onionprobe - Jim: Using Shadow @ Tor - To test and tune tor's new congestion control algorithm, we've been using the [shadow] simulator to evaluate the performance of proposed changes. I'll begin by showing how to set up and run a tiny simulation with a web server and a client, and then show how we incrementally build up from there to push-button realistic Tor simulations run in Gitlab CI. [shadow]: https://shadow.github.io/ - PieroV: New censorship circumvention in about:connect in the Tor Browser. - Richard: update about Blueprint work on Gosling and show off some very hello world functionality. -- pronouns she/her/they GPG Fingerprint EE3F DF5C AD91 643C 21BE 8370 180D B06C 59CA BD19
