Wow. What a post mortem. Rather than Monday morning quarterbacking how many ways this could have been prevented, I'd love to hear people sound-off on things that unexpectedly broke. I, for one, did not realize logging in to porkbun to edit DNS settings would become impossible with a cloudflare meltdown

That's unfortunate. I'll need to investigate whether Porkbun plans on decoupling its auth from being reliant on CloudFlare, otherwise I will need to migrate a few domains off of that registrar.
