I dont know how the federation works for peertube, but i guess that the most logical outcome of one specific instance going down is all videos on that instance being unavailable, while the rest of servers working fine.
I think its because images are quite small in size compared to videos, meaning that not everyone can store so many of them. Even on lemmy, some instances are not caching posts from other instances, even if they are federated.

That would be unfortunate. When lemmy.world goes down, I think all their content is still available on every instance that federated with it.
