This is a 7th level comment. Synu below[0] has a 9th level comment, and I've seen nested comments go quite a bit further.
I think there is no nesting maximum (or if there is, it's much bigger than this). There's a limit which stops you replying to a comment immediately, to prevent super long quick-fire arguments.

Ah, sorry, misunderstood you. You can’t rely on them to change their host records when they’re down.
If you want CDN-independent automatic failover, look into anycast with two providers. If one of them is Cloudflare, use the tier that lets you manage your DNS elsewhere.
There's a huge difference in changing nameservers for a domain and simply changing host records.
