CDN Usage

Checks if the site appears to be using a Content Delivery Network.

What is this check?

A Content Delivery Network (CDN) is a network of servers distributed geographically. When you use a CDN, your website's files are stored on all these servers. Users are then served files from the server that is physically closest to them.

Why is it important?

CDNs dramatically reduce latency and speed up page load times for users around the world. They also help handle traffic spikes and can offer additional security benefits.

What is the impact?

For any website with a global or even national audience, using a CDN is one of the most effective ways to improve performance and reliability.
