An analysis of 44,143 European companies that use a CDN found that 89.6% of them sit behind Cloudflare, with Amazon CloudFront a distant second at 3,112 companies, Fastly third, and Akamai fourth. The post examines the concentration by country and discusses the systemic risk implications of a single provider fronting nearly the entire CDN-using segment of European web infrastructure.

Chris McCabe at CipherCue went through their tracked database of European companies to identify which CDN fronts each one's website. Of 44,143 companies where a CDN was detected, 39,547 were behind Cloudflare — 89.6%. The next largest provider, Amazon CloudFront, served 3,112 companies, and Fastly came third with 1,299.
The piece notes that Amazon's figure is inflated by companies whose origin happens to sit on AWS rather than deliberate CloudFront adoption, making Fastly a cleaner benchmark for an intentional CDN choice. Cloudflare's share is consistent with, and slightly above, the 84.1% figure W3Techs reported for the same period across all tracked sites.
Key points
89.6% of CDN-using European companies use Cloudflare as their front door
Amazon CloudFront is a distant second; Fastly third with 1,299 companies; Akamai fourth with 396
The count is among CDN-using companies only — not all European web presence
Amazon's figure is partially inflated by general AWS hosting rather than deliberate CDN selection
Country-level breakdowns show similar concentration patterns across the eight largest European markets
Concentration means a Cloudflare outage would be a correlated failure across the majority of the European CDN-backed web
Why it matters
CDNs are a shared dependency: every site behind a provider fails together when that provider fails. Near-90% concentration in a single CDN represents a significant systemic risk for European web infrastructure — an outage, policy change, or regulatory intervention at Cloudflare would have simultaneous effects across the majority of the continent's CDN-using sites, regardless of what any individual company has done for resilience.
