It seems that the clients we've been working with over the past couple of years have no idea what a CDN is, let alone what an internet backbone is or what N+1 redundancy is.
Now, years ago, back in the early to mid 2000's, we would get a fairly regular flow of people wanting to know who the provider was, mainly because they were moving their ecommerce store from a competitor because it was slow and they didn't want to face the same thing. Same with the "who owns your server" question - MOST did not care who owned the server, but as a hosting company we were proud to say that we owned the machines (until we offloaded everything 🙂)
I think it's more of something the hosting company cares about and less what the client thinks. Sometimes we brag or promote things that are often only important to ourselves. The fact that all servers are running 128GB of RAM and are using Raid-50 SSD drives means absolutely nothing to 99% of clients.
