Thank you for your reply @chekohler.

Have they deployed anything? have they signed up any commercial clients? Have they proven their network to be superior and cheaper?

Well, NOIA has already deployed their Testnet and CDN Alpha. Every user can participate by running a node, which means that decentralized global network has already started to grow. There are already almost 5000 nodes around the world thanks to which website operators can use CDN Alpha in order to deliver their content.

Note that in order to create a stable and reliable decentralized network there has to be more nodes. That's why I encourage people here on Steemit to set up their own one. It is not the case of centralized CDN where you can just pay and set up necessary infrastructure. Deploying global decentralized network needs a lot of time.

other CDN projects both central and decentralized are much further on!

Which decentralized CDN project do you mean? I don't know any other.
