Universal CDN or UCDN is a content delivery network by XBT Holding, a global hosting and network solutions provider headquartered in Luxembourg. The company offers a wide array of services, which includes file hosting.
The network map of UCDN is relatively small: according to our information the company has 12 points of presence (PoPs).
HolaCDN is the video CDN from Hola, an Israel-based company known for their Hola VPN and peer-to-peer (P2P) technology, and P2P data mining service Luminati.io.
The solution lets customers combine their own CDN with the network of HolaCDN, to optimise video delivery. The delivery process takes place in two phases:
Customers can integrate the CDN with a variety of existing, third-party video players or use the Open Source Hola Player.
HolaCDN does not publish their network map or the amount and locations of their of points of presence (PoPs). Their network does not need to be extensive due to the nature of video loading: only the initial chunk needs to be served out quickly, what follows is less relevant. So, as far as their network goes – we can only guess.
