“Since Docker is a US company, we must comply with US export control regulations. In an effort to comply with these, we now block all IP addresses that are located in Cuba, Iran, North Korea, Republic of Crimea, Sudan, and Syria. If you are not in one of these cities, countries, or regions and are blocked, please reach out to https://hub.docker.com/support/contact/ “

would you guess, support is banned as well
also absolutely certainly no russian IT companies have local mirrors or VPNs to download docker images

and I don't remember the whole russia getting under export restrictions since otherwise they would ban it much sooner
