The article says the reason the content owners would want to do this is to “move them away from the congestion of the Internet.” The problem with this idea is that neither HBO, Sony nor Showtime owns their own CDN. They rely on third-party CDNs like Akamai, Limelight and Level 3 to deliver their content and these CDNs already have their servers inside ISP networks, or connected directly to them via interconnection deals. That’s the main value of using a service based CDN is to avoid congestion, which HBO and others are already doing.
