CDN

A Content Delivery Network (CDN) caches the static assets of your website (images, CSS, JavaScript, fonts, sometimes HTML) on hundreds of edge servers worldwide. Instead of sending every request to your origin server in Nuremberg, the Cloudflare/Akamai/Bunny/Fastly node near the visitor responds — latency typically drops from 200 ms to 20 ms and origin load drops by 80–95 %. Modern CDNs also offer DDoS protection, WAF (Web Application Firewall), HTTP/3, automatic image optimisation and free TLS certificates. Important for GDPR-compliant hosting: not every CDN routes requests within the EU and IP addresses may be logged in the US — providers like Bunny CDN (Slovenia) or Cloudflare with 'EU-only routing' address that.
