And I've never said anything about self hosting email.
I was talking about client projects. Hosting email isn't a client project and is something I wouldn't selfhost either.
When I mean creating projects in the cloud, I'm talking about using the big 3 Google, Microsoft and Amazon cloud. I even explicitly mentioned azure...
Netlify is build on top of AWS and for them, it's useful for actual scaling on the "edge". But most sites on netlify don't need their edge capabilities.
And cloudflare is one self hosting it on more edge locations ( i think they could even join the big 3 soon)
And still, some customers had issues 21 days ago with netlify DNS. So those clients spend time on that too and didn't knew what was happening at first

But i guess those issues don't count as "maintenance/work" :)
