Alexa and Fortune 500 CDN Marketshare - 2 Sep 2014

This post provides marketshare analysis for CDN services and top Alexa and US Fortune 500 websites. We compile this marketshare using a variety of techniques including CNAME chain analysis, ASN and IP/CIDR matching, multi-level site crawling, and related domain associations. We attempt to filter out known white labeled SaaS sites using a filter list. The network identifiers we use for marketshare correlations (CNAME regex, ASN, and IP/CIDR) are available via our Get Network Identifiers API method.
