Content Delivery Networks improve your websites performance by moving web resources closer to the end user for faster retrieval. On a typical website 80% or more of the volume of the site 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 your webservers, and improves performance for you visitors. The more requests we cache for you, the less requests need to be handled by your webserver and the beauty of it is, its all readily available when you need it, there's no need to scale up should you have a sudden burst of visitor traffic.
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. At this time 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 nodes across the globe but you actually may have access to only a fraction of their locations.
Configuring caching is as easy as 1 click from our portal and the CDN will obey all of the cache-control headers that are on your webserver. Should you wish to override your cache-control headers you can enable "Forced Caching" and direct it to cache any and/or all URLs or file types you specify. As with all of our services its fully managed, you don't have to do a thing, let us know what you want to do and our engineering staff will enable it and customize it for you.
DOSarrest CDN is included in the cost of your DDoS protection.
