Case Study: AO.com achieves faster site performance and lower costs with Cloudflare

AO.com - Customer Case Study

AO.com is the UK’s largest online-only electricals retailer, expanding from its 2000 start into Germany and the Netherlands. During that expansion they ran into problems with their CDN: unexpected high edge-traffic charges, a customer-impacting outage, and poor escalation left them questioning the provider’s cost-effectiveness and long-term suitability.

They switched to Cloudflare for built-in security, no overage charges, Argo Smart Routing, Tiered Caching, Workers, and Cloudflare load balancing. The move delivered measurable gains—page loads dropped by 1.7 seconds, Apdex-satisfied requests rose by 10%, page sizes fell by about 50%—while cutting costs, simplifying migration, improving resilience, and providing more responsive support.
