If this was the case, and theres tons of financial incentive to do so, wouldnt cloudflare,etc, block not based on the reported 'country' but some fuzzy heuristic that knows what country it comes from? hops?
- gpm 11mo agoThey've got enough points of presence that they ought to be able to narrow most people down to a reasonably small circle just by speed of light - unless they're intentionally increasing their ping or on some terribly congested network or something.
- rootsudo 11mo agoThe fuzzy heuristic can just be ping speed. Can’t beat the speed of light (yet.) But cloudflare already is toxic, doable third party cookies - friction nonstop, etc.
- seszett 11mo agoThat might work in big countries like the US, but in western Europe it's basically impossible to tell whether a connexion originates from London, Paris, Brussels or Amsterdam just by hop count or latency. Even just jitter in router response time is already higher than the difference in latency due to speed of light between those locations. And just France is large enough that a connexion to some IP in France might legitimately travel further or not compared to a connexion to some other country, from basically any vantage point you might be looking from, and might or might not round-trip through Paris, adding potentially up to 1500 km of uncertainty in the path. Identifying the interchanges the packets go through can help though, but not as much for residential ISPs.
