What is a CDN?
CDN is an abbreviation for Content Delivery Network – a chain of servers that are used to deliver static cached content to end-users, basing on their location. Sounds complicated? Let's clear it up.
Generally, users opening your WordPress blog are redirected to the server hosting it. And your server is located in a server from a datacenter. Thus, each visitor accesses this one server when opening your website. If you have thigh traffic, a server may be overloaded, which will lead to site or server crash, or loading slowing. That's when a CDN appears to be useful: this is a network of servers spread around the world. When you use it, all static content is being cached and stored on these servers. Static content is images, CSS files, JavaScript, Flash, etc. And when someone visits your site (residing on an original server), CDN redirects a user to the server located as close to him as possible (of course, a server comprising this network).
For instance, if your head server is located in San-Diego, CA, and users from Ireland are trying to access it, they will be redirected to a server located in London, e.g. the one which is closer to them. That allows to reduce the number of hops for the information to come to end users.
The distance between the user and the web server has direct influence on load time. Distributing the content between several geographically dispersed servers, you increase page loading for your site visitors. That's when CDN appears to be useful. To put it simply, the closer a CDN server to user is, the quicker the content and site pages will be loaded.
