Your general explanation is all good, but it never seems like any of the platforms built for live events really have issues delivering content. I don’t think the issue is so much that streaming live broadcasts is insurmountable as it is that Netflix specifically doesn’t have their architecture managed in a way that works well with big live events. They lean heavily on having their content cached close to the end users and don’t have a lot of experience at real time.
All the time.
Pretty much never intentionally, though. I’m just bad at keeping up with people.
