Our CDN is a content distribution network (or content delivery network) of physical, optimised servers across the world that cache the content of your website served from our platform. Cached content of the data is stored at CDN nodes around the world - customers from around the world will connect to those CDN nodes instead of directly to our local network, this will mean they're served content faster and your websites will load quicker.
By deploying servers around the world, it means that you have the option of serving both static and dynamic elements of your website closer to your visitors. You have full control over this and also have the option of completely disabling this if required.
If you've updated your website and want to ensure all users are seeing the latest content before the cache expires, you can also run an instant Cache Purge. The more content you cache, the faster your website will load.
Our Dynamic Cache provides the ability to cache any resource at our edge by using public Cache-Control and Expires headers. Once enabled, you can start storing content in this cache by configuring your application to emit those headers. Any responses that contain a cookie will not be cached.
Combined with StackCache, this gives you full page dynamic content caching ensuring rapid TTFB times for all resources regardless of visitor location. Advanced users can check the output of the X-CDN-Cache-Status header to see whether a resource was cached.
Customise a number of Edge Caching options best for your site.
At any time you can clear all cached files which will force all edge servers to fetch fresh copies from your site. Purging the cache may temporarily degrade performance for your website.
Why would I need to Purge?
If you have made changes to your site and you wanted to see the changes reflected immediately then you may need to purge the cache. However, our CDN will fetch your sites for you every hour to make sure the freshest content is served.
You can temporarily disable all caching to allow you to complete development tasks on the website without worrying about cached data. Caching is then automatically re-enabled after a period of 3 hours.
Use our Web Optimisation suite to automatically apply web performance best practices to optimise your website and improve your page speed. All of our optimisation tools are flagged by a "Risk" factor - Low Risk, Medium Risk and High Risk. If you are unsure which tools to enable we offer a One-click Optimisation which applies the most popular optimisation filters that should help improve page loading times without risking website functionality.
Our CDN allows you to block IP addresses, entire subnets or even whole countries. Automatically select a country from a dropdown list to block all IP addresses from that country (relies on GeoIP IP address data).
Block by IP address with Wildcards and CIDRs. For example, both 192.168.0.0/24 and 192.168.0.* would block all IP addresses between 192.168.0.0 and 192.168.0.255.
Monitor traffic to your sites across our CDN (Content Delivery Network), showing bandwidth, hits, SSL hits, errors and geographic distribution.

Select to view the traffic distribution over a time period of the Last Hour, Last Day or the Last Week.
From your Account Control Panel, see an overview for all hosted sites and their current CDN configuration. You can enable and disable the Global Edge Caching, Dynamic Caching and our Web Optimisation "Safe" recommendations from one place. You can globally also Purge Cache for any or all hosted sites. A direct login link to StackCP for each site is also accessible to login and refind any CDN settings as well as view the statistics.

Integrating your website into the CDN will bring many advantages for your traffic and conversion rates. The Content Distribution Network speeds up your site and brings content closer to your visitors, regardless of their location in the world, by replicating it on multiple servers. The information is sent faster and latency time (which can be very long for users located on other continents) is significantly reduced. CDN gives your site a real competitive edge, by enhancing performance and improving improve your search engine ranking as a result.
We provide our CDN at no extra charge and it is included an all hosting packages across all of our platforms. Other providers might try to sell it as an extra - we include it!
We currently utilise an exclusive number of very well connected datacentres in Northern America and across Europe - These exclusive POPs are usually used by transit providers and hence provide the very best latency using the smallest number of POPs. We essentially pay the premium to place hardware directly in "carrier hotels" and neutral datacentres that all traffic from a region will traverse through.
