Anti-censorship team

About us

Welcome to the anti-censorship team page. The anti-censorship team is a group of Tor people who make Tor reachable anywhere in the world. We analyze censorship attempts and develop technology to work around these censorship attempts.

One of the reasons we are not listing the names of the team members here is because we want to keep the team open to everyone. You're on the team if you're participating in discussions and development, and you're not part of the team anymore if you decide you want to move on (which we hope won't happen).

Excited about joining the team? Here is more information on how to get started.

IRC meetings schedule

We use IRC for our weekly meetings and we meet on the OFTC network in the #tor-meeting channel. The meeting takes place each Thursday at 18:00 UTC and typically lasts for an hour. This page can tell you what time this is in your part of the world. Sometimes, we have to cancel our meeting but we announce cancellations on our mailing list. Besides, our meeting pad always shows the date of the next meeting.

If you want to get involved in Tor's anti-censorship work, try to show up to the team meeting! To get an idea of what we discuss in our meetings, have a look at our Riseup pad for 2019. In a nutshell, we use our weekly meetings to:

  • Make announcements to the team.
  • Discuss topics like our development roadmap, team processes, or code architecture.
  • Ask for help with whatever we're working on.
  • Coordinate code review.

People on the anti-censorship team use the pad to keep track of what they did the past week, what they plan to do next week, and what they need help with. If you missed a meeting, fret not! We post log files of our meetings on the tor-project mailing list, typically with the string "Anti-censorship meeting notes" in the email's subject line.

Mailing list

For asynchronous communication, we use our anti-censorship-team mailing list. The list is publicly archived and available for anyone to sign up, so feel free to participate! Among other things, we use this mailing list to coordinate meetings, send announcements, and discuss all matters related to the anti-censorship team. Note that for development-related topics, we use the tor-dev mailing list.

Becoming a volunteer

Thanks for volunteering with us! There are many things that we need your help with:

  • Do you think that Tor (or one of its pluggable transports) is blocked in your country or network? Let us know!
  • Do you know how to code? Come help us improve one of our software projects! See below for more details.
