[ooni-talk] Measuring DoT/DoH Blocking Using OONI Probe: A Preliminary Study

[Maria Xynou]

Hello,

Last year, OONI wrote a research paper ("*Measuring DoT/DoH Blocking Using
OONI Probe: A Preliminary Study*") which was presented at the Network and
Distributed System Security Symposium (NDSS'21) as part of the DNS Privacy
Workshop. You can read this paper here:
https://www.ndss-symposium.org/wp-content/uploads/dnspriv21-02-paper.pdf

This study involves an *investigation of encrypted DNS (DoT & DoH) blocking
in Kazakhstan, Iran, and China* with a new OONI Probe experiment
(DNSCheck).

Today, we're publishing a blog post with a *summary of findings* (and video
presentation): https://ooni.org/post/2022-doh-dot-paper-dnsprivacy21/

You can also find a summary of findings through this Twitter thread:

You can help contribute measurements on encrypted DNS blocking by running
OONI Probe: https://ooni.org/install

Huge thanks to community members who supported this study!

Thanks,

Maria.
