Comparison of CDN service

I am planning on offering video downloads (NOT streaming!) using a CDN (which means a Content Delivery Network). I have a list of CDNs here [login to view URL] Now the most important for me is the price per GB. But there are other details I would like to know, such as number of centers, price per month (if any), price of the first TB, price of the 1,000th TB (i.e., what's the price decreasing dynamic based on volume). The deliverable should be a table with all the CDN providers listen on that Wikipedia category, with the follwing columns: CDN Provider / URL / E-mail address of contact person / starting price per GB / cheapest price per GB / number of centers / price of the first TB / price of the 1,000th TB. ## Deliverables Obviously I will need a link or any suitable proof for your results.
