8.8.8.8 is anycast, it is announced locally in many places around the world.

Is there a local instance of it in Russia? What happens when that server can’t reach any upstreams?

Yes there is, but if there wasn't it's easy enough for a government controlled provider to advertise it (and 1.1.1.1 etc).

China (and others) can also simply intercept all udp traffic to port 53.

There is. Only Google can answer the second question with certainty, but I'm 99% sure its upstreams are http://root-servers.org
