That is an impressive evolution for Cloudflare. This reminds me of DNS providers growing quickly. At a former org, we set up DNS with two of the biggest DNS providers in the event one of them went offline, as sometimes happened. I am curious how many of these domain owners have a secondary CDN account with inactive code toggles ready to switch to a backup CDN provider if this single point of success were to have issues. Do people account for this in their disaster recovery plans? Has anyone automated this with some form of GSLB health checks that will change their code toggles and/or DNS or use a secondary CDN?

Unless they are on the Business or Enterprise plans CF is the only authoritative DNS for the domain. The TTL is 24h so changing the nameservers would not be a quick fix.

That might be OK. If people are not on a business or enterprise plan then is it safe to assume they are not hosting anything critical or revenue generating? Or if they are, is it safe to assume they are not a publicly traded company?
