Content Distribution Networks

What is a CDN?

A CDN, or content delivery network, is a service that helps to accelerate the loading of static content on websites. This can be achieved by caching the content on servers located around the world so that it is closer to the user when they request it. CDNs are often used for images, videos, and other types of media which are typically static and do not change frequently.

 How Does a CDN Work?

A CDN is a content delivery network. It is a system of computers that are connected to each other and work together to deliver content. The main purpose of a CDN is to improve the performance of a website by delivering content from servers that are closer to the user’s location.

Content delivery network works by storing copies of content on multiple servers around the world. When a user visits a website, the CDN will direct them to the server that is closest to their location. This reduces the amount of time that it takes for the content to load, as it does not have to travel as far.

It can be used for any type of content, including images, videos, CSS files, and JavaScript files. They are often used by large websites that receive a lot of traffic from around the world.

For CDN the CDN service provider will ask for a change of nameserver. And change of nameserver may take some time for it to propagate and get established. During this time, your website may be unavailable if it is not cached in a large content delivery network. This propagation time may vary from 24-48 hours.
