A content delivery network sits between visitors and a company's servers. It caches pages and files in data centers around the world, absorbs attacks and often terminates TLS. Cloudflare is by far the most common choice on the open web; Akamai, Fastly and Amazon CloudFront are common at large enterprises and media companies.
Many sites use a CDN without choosing one directly, because hosting platforms put their own edge network in front of every deployment. The counts below include both.

How we find CDN and edge networks
CDNs show up in DNS (name servers and CNAMEs that point at the network), in the IP ranges a site resolves to, and in response headers such as cf-ray, x-served-by and x-amz-cf-id.
Every company on a tool's page links to the record behind the match. DNS is rechecked weekly and websites monthly, so tools a company stops using drop off the list.
