Recent reports from Tor users in Russia indicate an escalation in online censorship with the goal of blocking access to Tor and other circumvention tools. This new wave includes attempts to block Tor bridges and pluggable transports developed by the Tor Project, removal of circumvention apps from stores, and targeting popular hosting providers, shrinking the space for bypassing censorship. Despite these ongoing actions, Tor remains effective.
One alarming trend is the targeted blocking by Russia of popular hosting providers. As many circumvention tools are using them, this action made some Tor bridges inaccessible to many users in Russia. As Roscomnadzor and internet service providers in Russia are increasing their blocking efforts, the need for more WebTunnel bridges has become urgent.
We are calling on the Tor community to help us scale up WebTunnel bridges. If you've ever thought about running a Tor bridge, now is the time. Our goal is to deploy 200 new WebTunnel bridges by the end of this December to open secure access for users in Russia.
How to run a Tor WebTunnel bridge
On the International Day Against Online Censorship in March, we published a blog post introducing WebTunnel: "Hiding in Plain Sight". Setting up a WebTunnel bridge requires some system administration skills, but we've streamlined the process to make it as straightforward as possible.
1. Using Docker: We offer a Docker image that simplifies deploying the Tor bridge and WebTunnel transport. Some additional configuration of your web server is required.
2. Ansible automation: A WebTunnel Ansible role, created by community member Jacobo Nájera, provides another way to set up a WebTunnel bridge quickly.
You can find the technical requirements in our WebTunnel guide. In short, you'll need:
- A static IPv4 address (preferred)
- A self-hosted website
- A valid SSL/TLS certificate (e.g., Let's Encrypt)
- Bandwidth usage: at least 1 TB/month, but more is recommendable.
Important: Avoid using free shared DNS services, as they are frequently blocked in Russia and other regions. Consult our crowdsourced Good/Bad ISPs page for finding a home for your WebTunnel bridge and avoiding popular hosting companies.
Bridge campaign rules for participation
The campaign starts today, November 28, 2024, and will run until March 10, 2025. As a token of our appreciation for your volunteer work, we're offering a Tor t-shirt to operators who run 5 or more WebTunnel bridges during this period. Please note: Only one t-shirt will be awarded per operator. See the technical requirements below to participate in the campaign.
Technical requirements for campaign
- Operators must run one WebTunnel bridge per IPv4. It is acceptable to use multiple subdomains or distinct domains.
- Include a valid email address as your contact information. Or we won't be able to confirm and validate your participation in the campaign.
- Maintain your bridges running for at least 1 year.
- Ensure your bridges have a solid uptime, operating close to 24/7. Reboots for updates are fine.
- Your bridge must remain functional during the campaign period.
- Do not host your bridges with Hetzner.
How to participate
After spinning up and verifying that your five WebTunnel bridges are working, confirm your participation by emailing [email protected] with the following template:

Russian censors targeting pluggable transports
Tor-powered applications like Tor Browser include built-in censorship circumvention features, but censors in Russia are increasingly targeting these mechanisms. For example, user reports suggest that obfs4 connections are being blocked on some 4G mobile networks. Despite this, obfs4 remains the most widely used pluggable transport for Tor users in Russia. Snowflake has also experienced partial blocks from certain providers and Tor's Anti-Censorship Team have been investigating.
Addressing these issues - analyzing censorship tactics, developing fixes, and implementing updates - takes time. This makes WebTunnel bridges an immediate and critical solution for keeping users connected.
Tor-powered applications are critical for combating online censorship in heavily restricted regions. In a country where "the biggest banks were instructed to punish customers using credit cards to pay for VPN services", free and open source tools like Tor are some of the few remaining alternatives for keeping users connected.
Background: Tor blocked in Russia (2021)
In late 2021, the Russian government attempted to block Tor, as we detailed in our blog post. Despite the censors' best efforts, Russian users were able to circumvent the block using Tor bridges.
Upon launch of Webtunnel in early 2024, we only had 60 WebTunnel bridges. Today, the number has more than doubled to 143. However, we must improve our efforts to meet the rising demand and counter the evolving censorship landscape.
If you've ever considered running a Tor bridge, now is an excellent time to get started. Please help us spread the word as your help is urgently needed.
