Ok but isn’t peertube defederated?

Which means (unless I grossly misunderstand the concept)

that your video(s) are stored not only on your own server but also shared out to other servers which also keep a copy cached.

So in this scenario it would be very much immune to these concerns because your video(s) will be streamed from the closest server to you which has a copy, meaning you will always get the best throughput no matter what your physical location is or what it was when you uploaded.
