Internet censorship in Iran and Russia: Elevated demands for Snowflake proxy and WebTunnel bridge instances

Introduction

The Iranian Liberation Revolution and Putin’s aggressive war are each accompanied by powerful national internet censorship. Facebook, Twitter and Instagram are already blocked, more services are likely to follow. Since all critical media are now banned in Russia and none existed in Iran, internet services are a last way to get independent information, to organize and also to report on the local situation to the rest of the world. Only in this way is an effective opposition and active civil society still possible.

For a period of time, people in Iran and Russia were able to use digital tools to bypass internet censorship. They used so-called VPNs (Virtual Private Networks) or anti-censorship software called Tor Browser. Unfortunately, the respective dictators have upgraded the Internet censorship systems since the beginning of the war or since the beginning of the revolution, so that these digital “tools of freedom” no longer work easily. But now there is a new approach to circumvent internet censorship. Everyone here in Germany can help with this, without great technical skills. A web browser with internet access is sufficient.

How-to

To provide anti-censorship infrastructure, you can run a Snowflake proxy either standalone on a server, or by installing a plugin into your browser.

To consume anti-censorship infrastructure, you can use the original Tor Browser on your workstation, or Orbot on your mobile phone. Provided by the Guardian Project, it brings trusted connections for Tor to Android and iOS.
