Based on the comment from bobfunk, it seems they do have a backup plan but not all customers use a configuration which takes advantage of it.

A backup plan that does not service apex domains is not really a backup plan.

It sounds like it does handle apex domains, but only if you're using Netlify DNS or a provider which supports CNAME flattening. Assuming the potential problems with not doing so are disclosed during setup (not sure if they were) that actually seems pretty reasonable to me.

I run the Netlify Support team, and this statement from @michaelmior is correct: apex domains are served using redundant, global CDN if you use Netlify's DNS hosting, or Flattened CNAMEs from Cloudflare.
