I've came across websites that return a 403 to ANY IP located in Russia for some reason. Official website for NSA's Ghidra is one example. Had to use a VPN because I was having none of that bullshit.
I once had a different story — some openstack Q&A website wasn't unavailable from Russia. Turned out it wasn't the website who was blocking russian ips — it was roskomnadzor carpet-blocking whole IP ranges of cloud providers.

Oh yeah, forgot about it. RKN block is usually an SSL error, a timeout, or a page from your ISP saying "this is blocked by the government, sorry". Never a 403.
Thankfully, smaller ISPs are terrifically terrible at complying with this.
There are sites that don't work for any address from EU, because they they don't want to comply with GDPR. Not very common, but I have hit a few.
However, it's a difference whether a company does not want to serve you or whether a country that says it brings freedom to the world stops information flow for some. China is criticized for the big firewall. When the US does it to others, it's in the name of freedom.
