# Nearly 90% of European Companies Using CDNs Rely on Cloudflare Cloudflare dominates the CDN market in Europe with an 89.6% share. - **Source:** [Hacker News (news.ycombinator.com)](https://brifing.si/source/13c923cd-6d99-442b-9b8b-1181f4d8cd91) - **Published:** 2026-09-08 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/705147c5-e9e7-47a6-ab60-4cf93ae5f10b ## What is a CDN? A content delivery network (CDN) sits in front of a website, handling requests through edge servers. These servers cache content, terminate TLS, filter traffic, and pass requests back to the origin server. This makes CDNs a shared dependency; if a CDN fails, all sites behind it go down simultaneously, regardless of their individual configurations or origins. ## Cloudflare's Market Share Among 44,143 European companies using CDNs, 39,547 rely on Cloudflare, representing an 89.6% market share. This figure aligns closely with W3Techs' global estimate of 84.1% for Cloudflare as of July 2026. The study focuses on companies where the CDN provider is identifiable, excluding those serving content directly from their origin servers. ## Competitors in the CDN Market Amazon CloudFront ranks second with 3,112 companies, though some of these may be AWS users rather than deliberate CloudFront adopters. Fastly, a pure CDN provider, comes third with 1,299 companies, while Akamai, the oldest player, is fourth with 396. Double counting occurs when companies use multiple CDNs, inflating smaller vendors' totals. ## Country-Specific Breakdown Cloudflare dominates across all major European markets. The UK leads with 15,846 companies using Cloudflare, while Germany has the lowest share among large markets at 81.4%. The Netherlands shows the highest concentration, with 19 out of 20 CDN users relying on Cloudflare. ## Risks of Market Concentration When most of a market depends on a single CDN provider, outages become systemic. Cloudflare has experienced three global incidents in the past 15 months, each caused by internal errors rather than external attacks. These incidents highlight the risks of shared dependencies in critical infrastructure. ## CDN Detection Methodology The study identifies CDN usage through HTTP response headers and DNS fingerprints. Companies using unrecognized or misconfigured setups are excluded. Double counting occurs when a company uses multiple CDNs, but Cloudflare's share is calculated against the total CDN-using set. ## Skew Toward SMEs The dataset skews toward small and mid-sized enterprises (SMEs), where Cloudflare's free tier is particularly strong. This concentration does not necessarily reflect usage among large enterprises, which may have different CDN preferences or in-house solutions. ## Implications for Resilience The dominance of Cloudflare in Europe's CDN market raises concerns about resilience. Independent suppliers offer fail-safe diversity, but this advantage diminishes when most companies rely on a single provider. Incidents affecting Cloudflare can disrupt a significant portion of the market simultaneously. ## Sources covering this story - https://ciphercue.com/blog/european-cdn-concentration-cloudflare-nine-in-ten — --- _Summary written by Brifing from the original reporting.
