How to read this
- Each site counted once: a site split across providers is split evenly. Traffic-weighted (Fortune 500): busier hostnames count more.
- "AWS" means CloudFront plus sites served straight from AWS with no CDN. AWS WAF and Shield aren't counted on their own.
- Only AWS, Azure and Google Cloud are counted as hyperscalers. Cloudflare and Akamai are edge networks.
- Numbers refresh after each scan, using each site's and company's latest data. No changes over time are shown yet; that needs two weeks of weekly scans. Methodology.
