CDN & Hosting
366,796 of the 1,000,000 top sites in our Tranco top-1M census run Cloudflare (36.7%). A CDN, DNS resolver, and edge security network — the single most common CDN in the census by a wide margin. Detection is homepage-level HTML/header fingerprinting, so a site can run Cloudflare on other pages without it showing here.
