What's irritating to me are the claims that there's nothing distinguishing real time control plane state changes and config files. Most of us have an intuition for how they'd do a careful rollout of a config file change. That intuition doesn't hold for control plane state; it's like saying, for instance, that OSPF should have canaries and staged rollouts every time a link state changes.

I'm not saying there aren't things you to do make real-time control plane state propagation safer, or that Cloudflare did all those things (I have no idea, I'm not familiar with their system at all, which is another thing irritating me about this thread --- the confident diagnostics and recommendations). I'm saying that people trying to do the "this is just like CrowdStrike" thing are telling on themselves.
