On most networks in #Russia, access to OONI Explorer appears to be blocked by means of TLS interference.
Many measurements resulted in timeout errors & connection reset errors right after the Client Hello message during the TLS handshake.

On some networks in #Russia, we are able to automatically confirm the blocking of OONI Explorer based on fingerprints.
For example, OONI data shows that DNS resolution returns an IP that hosts a block page.

While Roskomnadzor mentioned their intention to restrict access to the Russian translation of circumvention tool reachability measurements, in practice, the restriction is far-reaching.
The block restricts access to all OONI data hosted on OONI Explorer.

On 11th September 2024, we received an email from Roskomnadzor, informing us of their decision to block access to OONI Explorer.
On the same day, OONI data shows that ISPs in #Russia started implementing the block.
