I am baffled seeing so much cloudflare fanboys here...
Cloudflare is everywhere, it sees everything, it holds everything, it has private keys for tons and tons of websites, it's subject to the absence of any privacy law in the US, but they are "nice". Wow.
Google also was nice. It used to give you good results. Twitter also was nice.
I really think that on the list of worst single points of failure, DNS is not one of them. Given how easy it is to actually switch. And given that cloudflare outages are not nearly as common, The times they do happen usually are only for half an hour or so.

Considering how I (try) to do bug bounties for money, it's bad for that, but otherwise, it'd probably be worse without it, considering how it seems a lot of developers seem to totally rely on it for reflected XSS protection.
