OONI reports of Tor blocking in certain ISPs since 2021-12-01

Globalcheck.net test result. I’m not confident in it — it reports that ajax.aspnetcdn.com is not accessible from cellular Beeline, MTS, MegaFon, Yota (all Moscow), and accessible only from Rostelecom.
However, I’ve performed tests to other known-working hostnames and it lists them as accessible. Strange.
