Hello folks, SNI based filtering is increasingly being observed around the world, so the OONI team worked on writing a new SNI blocking experiment.

In this blog post, we document the measurement of SNI based blocking in Iran based on our new SNI blocking experiment: https://ooni.org/post/2020-iran-sni-blocking/ Best, ~ OONI team. -- Maria Xynou Research & Partnerships Director Open Observatory of Network Interference (OONI) https://ooni.org/ PGP Key Fingerprint: 2DC8 AFB6 CA11 B552 1081 FBDE 2131 B3BE 70CA 417E
