A Content Delivery Network (CDN) is a group of servers located strategically around the world. These server locations are known as Points of Presence (PoPs).
Even if your site runs on the fastest server on the planet, it’s still limited by its geographical location. A WordPress CDN will decrease the distance between the individual user and the site’s resources, reducing both network latency and time to first byte (TTFB).
Depending on where the request is coming from, it automatically assigns the nearest CDN PoP to deliver the cached resources. The result is a faster website and a better user experience.
Apart from caching, many CDNs include other performance-enhancing features such as superior on-the-fly image compression, HTTP/2 support, hotlink protection, and additional security.
