Do I need a CDN?

Almost every website should have a CDN in front of it, but this free tool helps you see why.

A CDN (Content Delivery Network) gives you access to thousands of servers around the world, that temporarily host a copy of your site for you, massively reducing the time it takes to load your website.

If you're not using a CDN, every request to your website (including its resources like CSS/JS and images) gets routed slowly across the world to your server, greatly reducing your website's speed the further away from your visitors your server is.
