What are global servers (CDN)?
A CDN is a collection of servers located all around the world. When a web visitor accesses your website, the CDN will load cached versions of the static content. These are servers optimised for speed and are positioned to effectively serve a global audience.
Why do you need it?
A CDN provides a faster web browsing experience by loading your website from a server geographically closest to your website visitor. A CDN is ideal for websites that target a global audience and/or experience high levels or spikes in their website traffic. The server load is shared across many locations, making for a more consistent and stable website.
