    Thanks for the info. It’s very useful. I am sure that using a CDN definitely worth it even more than previously. Personally i would recommend Edgecast. It has SuperPOPs (points of presence) that are located on five continents. Those SuperPOPs allow the end user to get content almost instantly from the location that is the closest to the user. So the user becomes a loyal visitor an visits the website over an over again.
    Also the speed of a website affects the position of the website in all search engines. The faster the website is the higher search engine rankings it has.
    Edgecast constantly works to overperform other CDN networks improving its services. So the website’s owner may be ensure that his website is fast, secured and optimized with Edgecast. If anybody is interested you can read more obout Edgecast at
