CDN (Content Delivery Network)

A CDN (Content Delivery Network) is a globally distributed network of interconnected proxy servers designed to deliver website content to users with lightning speed, regardless of their physical location. If a website’s primary server is in New York, a user in London will experience significant latency (delay) while the data travels across the ocean. A CDN solves this by storing cached copies of the website’s heavy assets (images, videos, CSS) on servers in London, Tokyo, and Sydney. By serving the data from the server physically closest to the user, a CDN drastically improves global page load speeds and Core Web Vitals metrics.

CDN (Content Delivery Network) Simplified

A CDN is a massive network of servers spread all over the world. Instead of forcing someone in Europe to download your website all the way from your server in America, a CDN copies your website to a server in Europe, making it load instantly for them.
