To minimize the distance between the users and website’s server, a CDN stores a cached version of its content in multiple geographical locations also known as points of presence, or PoP. Each PoP contains a number of caching servers responsible for **[content delivery](https://www.mindstick.com/interview/33679/what-is-content-delivery-network)** to users with its proximity.

In another words, CDN puts the content at many places at once, providing with superior coverage to users. For example, when someone in London accesses US-hosted website, it is done through a local UK PoP. This is much quicker than having the user’s requests, and their responses, travel the full width of the Atlantic and back.

This is how a CDN works.
