The main reason to sign up for content delivery network services is to ensure faster delivery of content to end-users. Because of latency problems, the numbers of visitors to your site may decline. Visitors are not keen to stay on a site if its pages take very long to load. This delay interval is typically because of the huge physical distance between the end-user and the web server. So the content delivery network is designed primarily to make sure that this distance does not come in the way of fast content delivery.
