The most surefire way to know if a site is behind Cloudflare (orange cloud is on) is by hitting /cdn-cgi/trace (e.g. https://news.ycombinator.com/cdn-cgi/trace) which is the debug output from Cloudflare’s HTTP server. There’s no way to my knowledge that route can be disabled or overriden.

Anyway, no, HN is not on Cloudflare, at least at the moment.

https://www.cloudflare.com/cgi-bin/trace/ is a 404

That's because it's cdn-cgi and not cgi-bin.
