A new analysis of European company websites reveals significant concentration in the content delivery network market. Among 44,143 European companies running a CDN, 39,547 are behind Cloudflare—89.6% of the CDN-using set, according to CipherCue’s tracking data.
For context, W3Techs reported Cloudflare at 84.1% of sites where the reverse proxy provider can be identified as of July 2026. CipherCue’s European figure runs slightly higher, measured the same way—as a share of identified CDNs rather than all sites.
Cloudflare’s dominance varies by country. The Netherlands shows the highest concentration at 95.6%, followed by the United Kingdom at 93.2% and Poland at 92.6%. Spain and Ireland are the lowest at 78.8%, while Germany—the largest market in the analysis—sits at 81.4%. Even the lowest figure represents four in five companies.
The other major CDN providers trail far behind. Amazon CloudFront ranks second at 3,112 companies, though CipherCue notes this figure includes companies whose origins sit on AWS rather than deliberately choosing CloudFront. Fastly, a pure CDN provider, comes third at 1,299 companies. Akamai, historically the oldest CDN vendor, ranks fourth at 396.
This concentration creates what CipherCue calls a resilience problem. A content delivery network sits in front of a website, serving cached content and filtering traffic before passing requests to the origin. When a CDN fails, every site behind it goes down simultaneously, regardless of whether those sites share anything else in common.
Cloudflare has published postmortems for three global incidents in the last 15 months. On November 18, 2025, a database permissions change caused a Bot Management feature file to exceed size limits, crashing core CDN service from roughly 11:20 to 17:06 UTC. On December 5, 2025, a configuration change made while patching a React Server Components vulnerability caused global disruption. On February 20, 2026, a cleanup automation task misread a buggy API response and withdrew 25% of BYOIP prefixes from the internet via BGP, lasting 6 hours and 7 minutes.
CipherCue notes these were not attacks but routine internal errors—a doubled config file, a patch applied at the wrong time, an automation job that deleted too much. The point is not that Cloudflare is uniquely error-prone; Fastly and Akamai experience similar bugs. Rather, when one provider fronts most of a market, its mistakes become everyone’s problem simultaneously. The analysis examined only the CDN front door, not origin servers or data residency, which remain independently hosted for most companies.
Key facts
- 89.6% of European companies using a CDN rely on Cloudflare, according to CipherCue analysis of 44,143 companies
- Cloudflare’s market share ranges from 78.8% in Spain and Ireland to 95.6% in the Netherlands
- Fastly ranks third with 1,299 companies, roughly one company for every thirty behind Cloudflare
- Three global Cloudflare outages occurred between November 2025 and February 2026, each taking most customer sites offline simultaneously
- Cloudflare’s outages resulted from routine operational errors: a database permissions change, a configuration change during vulnerability mitigation, and an automation task that over-deleted
