CDN & Hosting
375,539 of the 1,000,000 top sites in our Tranco top-1M census run Cloudflare edge/CDN (37.6%). Cloudflare's edge network, caching and routing site traffic through its global CDN and reverse-proxy infrastructure. Detection is homepage-level HTML/header fingerprinting, so a site can run Cloudflare edge/CDN on other pages without it showing here.
