CDN - Content Delivery Network

A CDN (Content Delivery Network) is a key concept used to make the Internet work.

Without getting too technical a CDN is basically a system created using a collection of connected servers that are located globally such that requests for data (content) is not reliant on a single server or a connection to that singel server.

The use of a CDN is pretty much transparent to both the Internet user and the content provider. Websites such as tempusfugit.me.uk may be connected through a CDN but it rather depends on the hosting service that I am using. The addage that you get what you pay for applies in spades here.

For a small website owner and operator there are things that you can do to mitigate the lack of CDN technologies, these would include the use of large platforms such as Wordpress.com. However, I believe that this comes at a cost with respect to creativity.

Clouldflare offer a free CDN services for websites such as tempusfugit.me.uk and it does have an account. The use of this is still to be investigated.

The W3.css is on a CDN

This is okay as long as the W3CShools website does not go down! I have only seen this once, but it could be a problem if I were to be demonstrating a website. Having the CSS locally also falls in-line with my development technique.
