In this case - given this and the other comments - I stand corrected! I would love to see some data on examples of this occurring in the wild - and it 100% makes sense that a congested CDN provider would impact neighbors. It would be great if someone could do a writeup on examples and the detection/mitigation strategies. Perhaps issues like these (alongside cost) are driving the DIY CDN adoptions (Apple being the exemplar but also Tesla etc)? Also the Pinterest example is a great real world example - and they do an awesome job especially given the size of that cache - so there must be so real value from a performance standpoint! Out of curiosity does it seem like these dynamic switching decisions are better at the server level or client level?
