I was having an issue connecting to Netflix earlier, until I used VPN. I momentarily wondered if Comcast was going back to their old practices of sabotaging streaming services from 10 years ago. DownDetector said Netflix was down, other sites worked, it makes sense that Comcast is up to no good, right?

But I don't use Comcast DNS. Netflix would be the only site I visited which has a peering agreement with Comcast. It makes more sense that the route between Comcast and Netflix is broken, regardless of my local DNS lookups being unaffected, than malfeasance on Comcast's part. The route from Comcast to VPN to Netflix, on the other hand, is unaffected.
