Signal is currently blocked in Iran. To help people in the country access Signal, we are republishing and revising a post that we originally posted in February, 2021 during a very similar situation in Iran.
If you are willing and able, please follow the instructions below to set up a proxy server that will enable people in Iran to connect to Signal. We are grateful to the community who pitches in to help each other during these moments.
If you are currently running a proxy, you will need to make some updates to ensure it continues to function. Update instructions are here.
