Cloudflare Terminates Service to Sci-Hub Domain Names
I am surprised that so many sites rely on cloudflare. I'm sure they provide some very cool services, but I would be concerned both from- a design perspective (they are a somewhat single point of failure for much of the web, and add complexity/potential vulnerability), and from- a control perspective, you are giving them control over your site and they have shown themselves a capricious in the past as well as vulnerable to legal coercion. (For instance, could a malicious actor take down a website by sending CloudFlare fake DMCA notices?)
