They'll block known VPN/Proxy endpoints I guess. I bet spinning up your own proxy/VPN will still work. Although they might block entire networks like EC2 and DigitalOcean too.
Exactly. Blocking down known VPN/Proxy endpoints gets them 99% mileage with minimal effort. I don't think they are looking for 100% coverage here.
Honestly, I doubt they even really care. This is probably just to keep from getting screwed over in some licensing deal. "Look, we really tried hard to stop this, I guess those internet-guys are just too good at getting around the system. Oh well."
The far easier method is with DNS services, I wonder if it will affect those too or this is just an official announcement and they will not do anything drastic.
Well those work by resolving some domains (like netflix.com) to their own tunnel endpoints, which then tunnel to a different country. They can then just block the endpoints' IPs. It's actually not that hard to set up, I did it a couple of years ago to tunnel youtube (which is pretty crippled for music in Germany) and some other services not available outside of the US to a server in the US. The DNS server was in Germany to keep latency low.
Yes I see what you mean, they have their own servers to proxy but then are able to hand off the actual video traffic. So presumably Netflix knows which are the Getflix and other service tunnel endpoints. I wonder if it will escalate with Getflix and other providers attempting to bypass such blocks.
