As yourself more the question, is your service that important to need 99.999% uptime? Because i get the impression that people are so fixated on this uptime concept, that the idea of being down for a few hours is the most horrible issue in the world. To the point that they rather hand over control of their own system to a 3th party, then accept a downtime.

The fact that cloudflare can literally ready every bit of communication (as it sits between the client and your server) is already plenty bad. And yet, we accept this more easily, then a bit of downtime. We shall not ask about the prices for that service ;)

To me its nothing more then the whole "everybody on the cloud" issue, when most do not need the resource that cloud companies like AWS provide (and the bill), and yet, get totally tied down to this one service.

I am getting old lol ...
