I’m not very familiar woth Tailscale but the procedure should be as simple as making sure all the traffic runs through the same exit node. Be aware that this might severely strain the upload of that exit node device bit from a technical point of view, it should work. Wait for someone that actually uses Tailscale to respond with details :) Edit: are you running tailscale on the machine that accesses netflix or on a router?
So you are tryimg to tell me that the operating costs of the CDN are the big reason they need money, not the fact they throw billions at crappy content productions? And that the little performance you would gain by stripping k8s would make a difference, especially wrt the huge additional administration effort and lack of automation this would introduce? Nah man, sorry but you are wrong here in many ways.
