Ah. Obviously.

So yeah, how is a CDN centralizing your infra? You could just have your CNAMEs point to a different provider or directly to your gateways. Or you could even go down the multi CDN path, and have someone like ns1 automatically redirect your CNAMEs to an alternate CDN on a per-geo basis to overcome local failures.

It's just another SaaS component in your system. You could self host if you're willing to take on the ownership challenge, and at certain scale it would even be more cost effective.
