Comment Doesn't prove anything (Score 2) 8
Using a VPN just pushes the traffic over a different path than direct from Comcast's network to Netflix servers. So now it's going from Comcast to Work (or wherever VPN server is) to Netflix. The path between Comcast and Netflix may just be saturated and now you've bypassed it. If a VPN works better for you, keep using it.
I'm not saying Comcast doesn't throttle it, but this isn't proof.
