Reasons to Use a CDN

A content delivery network (CDN) is a system of distributed servers that deliver web content to a user based on their geographic location. CDNs also provide protection from large surges in website traffic.

Here are 4 reasons that you may want to implement a CDN on your website.


51% of the web’s traffic comes from bots rather than humans, so it's important to keep your website safe from hackers and unwanted, malicious bots. 29% of web traffic comes from malicious bots.

Clever CDN services offer security from bots and unwanted website attacks. Users will hit the CDN server closest to them before they hit your website’s actual server.


With your website content distributed around the world, it also means that your traffic is spread across the network - which reduces the problem of a single point of failure.

Malicious traffic is intercepted before it reaches the web server. CDNs have algorithms which are able to identify DDoS traffic and kill it quickly. This keeps your core web server running, and avoid you having to run your own DDoS protection.


Everyone enjoys a fast website. Slow websites cause users to leave quickly. One of the usual issues with website speed is distance. The distance between the hosting server and your user's browser. The distance that the content travels makes a big difference in page speed and can definitely be a bottleneck in website loading speeds.
