43,958 of the 1,000,000 top sites in our Tranco top-1M census run Amazon CloudFront (4.4%). AWS's content delivery network, fronting origins on S3, EC2, or an external host. Detection is homepage-level HTML/header fingerprinting, so a site can run Amazon CloudFront on other pages without it showing here.
