But web2 is going (really) great once you depend on Cloudflare. And it is certainly not re-centralizing the whole internet with a provider that is a single point of failure. /s
Care to clarify so I could take the mandatory contrarian approach?
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.
Technically you could set up a separate DNS/failover somewhere else and use a backup reverse proxy/TLS terminator/CDN SaaS similar to CloudFlare, but then that somewhere else will be your point of failure.
