While it's certainly worthwhile to discuss the Technical and Procedural elements that contributed to this Service Outage, the far more important (and mutually-exclusive aspect) to discuss should be:

Why have we built / permitted the building of / Subscribed to such a Failure-intolerant "Network"?

Who's "we"? This is not a trick question, what specific people do you think acted wrongly here? I don't use Cloudflare personally. I don't run any of the sites that do use it. The people who did make the decision to put thier websites behind Cloudflare could stop, and maybe some will, but presumably they're paying for it because they think, perhaps accurately, that they get value out of it. Should some power compel them not to use Cloudflare?
