BBC Websites are officially blocked in Russia & China.
China blocks via DNS (returns incorrect answers). They probably also monitor for connections outside of China (e.g. using hosts file), I assume they block foreign DNS resolution.
Russia blocks mainly via TLS SNI snooping & connection termination, done by their major ISPs.
There's a big discrepency between the volume of requests we see between the two countries. I honestly don't know why.
Odd.
