Glossary: Web hosting
What is a CDN?
A network of servers around the world that keeps copies of your website's files, so visitors load them from somewhere nearby.
What it is
Without a CDN, every visitor loads your files from your hosting server, however far away they are. A CDN keeps copies of files such as images and stylesheets in many locations, and serves each visitor from a nearby one.
What it helps with
The main benefits are faster pages for visitors far from your server, less work for your server, and some protection from attacks that flood a site with traffic.
Does a small business need one?
If your customers are mostly near your server, the speed gain is smaller, although a CDN can still help. It won't fix a site that is slow because of its own software or very large images, so fix those too.
