What is a cdn

What is a CDN and how does it improve web page speed? A Content Delivery Network, or CDN for short, is a system of servers that deliver content to end users. The geographical location of the user determines which server will serve them the content.


This means that if someone in London types your website URL into their browser, the request will be sent to one geographical region while if someone from New York requests your website through their browser, they will be served content from another geographical region. So what exactly are the benefits of this? CDNs can reduce page load times by up to 50% on average!


This is because a CDN decreases geographical load times by serving content from the geographical location of the end user. In other words, it's like having multiple servers around the world to serve your website so that people everywhere get served at their nearest geographical server.
