What is "don't put your eggs in one basket" here? Your DNS has to point to something... and changing it will go through propagation delays, during which it will be down if you are banned suddenly.

It's not like you can have your domain/DNS somewhere else and point to Cloudflare IPs (to not put DNS and CDN in same basket). Cloudflare does not allow that setup.

You can't protect your website from your DNS provider or hosting provider suddenly kicking you off. You are going to be offline for a couple of days.
