Content Delivery Networks improve your website's performance by moving web resources closer to the end user for faster retrieval. On a typical website 80% or more of the content of a website is comprised of static elements that are the same for all users. By speeding up the delivery of this content the end user will be able to load the site faster.
Our primary focus is DDoS protection and by its design has to have massive bandwidth and processing capacity available all the time, making us a great CDN by any measure. When customers offload static requests to the CDN it lowers their bandwidth, reduces the load on their webservers, and improves performance for their visitors. The more requests we cache for you, the less requests need to be handled by your webserver and the beauty of it is, it's all readily available when you need it, there's no need to scale up should you have a sudden burst of visitor traffic.
"Our system allows our customers to turn a run-of-the-mill server into a powerhouse able to serve millions " Jag Bains, DOSarrest CTO
DOSarrest's CDN is highly customizable, allowing you to specify unique cache directives on resources as granular as individual URL's or file types. DOSarrest is fully RFC2616 compliant, you can use our fully featured control panel to define and or override your websites cache-control headers or you can manage your caching directives via the cache control headers from your webserver. All of our customers content is cached on all of our nodes in Europe, North America and Asia. This is not the case with some other CDN's, they may have many nodes around the world but you actually may have access to only a fraction of their locations, even if you do have access to all of their nodes because some of these nodes are actually rented from 3rd party hosting service providers that have different upstream providers in different locations, your performance may actually be worse for some web visitors, due to how Internet BGP routing functions.
All DOSarrest customers have access to all of our nodes which are owned and operated by DOSarrest using the same upstream providers in each node across the globe.
There are a number of features that customers can make use of to improve their website's performance.
