Wait, is this just a fad now? People just implementing security measures to specifically deny access from those countries, even for completely innocent services?
Seems to be so: in the past year I encountered notably more seemingly geoip-caused HTTP 403 errors than previously, often with CloudFront or Cloudflare, but usually they don't provide a list of blacklisted countries like that. It's rather surprising to see Hungary there, but not NK and Iran, assuming it's just political (and not a response to some attacks, or has to do with some legal issues).
