CDN & Hosting
13,716 of the 1,000,000 top sites in our Tranco top-1M census run Amazon S3 (1.4%). AWS's object storage service, often used to host static assets or entire static sites. Detection is homepage-level HTML/header fingerprinting, so a site can run Amazon S3 on other pages without it showing here.
