A content delivery network provides several features, firstly it allows a website to remove load from its web server by moving ancillary files onto another server for them to process, theoretically speeding up the website. Secondly a CDN is normally geographically dispersed to provide a regionally local copy of your data to the recipient. For example, a user in Japan will receive an image from your website from a server in Japan, rather than having to request it from the USA, if that is the original location of the media. CDNs are also suited for large distributions of data; this includes web video and large files as they are better equipped to handle the amount of data being requested.

The most detected CDN by BuiltWith is currently Akamai which are one of the early pioneers of the edge network; geographically dispersed content delivery.

Distribution is calculated from a cross section of website domains provided by URLs entered at BuiltWith.com and the Quantcast Top Million. Last calculated on February 28 2010

Analytics penetration is based on what BuiltWith can find and is typically based on popular 3rd party tools. Last calculated on February 28 2010.
