CDN (Content Delivery Network)
A globally distributed network of servers that delivers web content from the node closest to the user to reduce latency.
CDNs reduce TTFB and improve LCP by serving static assets (images, JS, CSS) and cached HTML from edge locations close to users. Popular CDNs include Cloudflare, AWS CloudFront, Fastly, and Akamai. For websites targeting global audiences, a CDN is one of the highest-ROI performance investments — reducing LCP by 200–500ms for remote users is common.
