It's hard not to use Cloudflare at least for me: good products, "free" for small projects, and if Cloudflare is down no one will blame you since the internet is down.
That is true. it is also the problem. It means the biggest providers do not even need to bother to be reliable because everyone will use them anyway.
But this is not really the case. When Azure/AWS were down, same as this one with Cloudflare: significant amount of web was down but most of it was not. It just makes more obvious which provider you use.
