Internet censorship and surveillance have gotten worse every year. Security matters more than ever as AI-driven vulnerability discovery gets better. The people we build for depend on our machines to reach the open Internet safely, and every one of those machines runs Linux. The kernel underneath is the part that arguably matters most. Our Tor…

Governments across the world continue to block & restrict access to the uncensored Internet, with many of them blocking & restricting the use of the Tor network as a result. Over a year ago, we launched Operation Envoy, an effort to help defeat those Internet censors. Operation Envoy originally helped with our vast deployment of…
How we accidentally broke our Tor exit relays
Making technology work how you expect it to, and keep it working that way can be difficult at times. Changes in configuration or software updates can put services into a broken or half-broken state, and we had the latter happen to us. In the spirit of transparency, we are writing about the painful discovery that…
New Tor bridge types for Operation Envoy

This is achieved by Unredacted operating Tor bridges, also known as Pluggable Transports. Tor bridges obfuscate (bridge) the connection a user makes when connecting to Tor so that it…

However the worst offenders are the ones you would typically suspect, China, Russia and…
