In 2014, Comcast debuted their CDN service. With their own CDN in place, Comcast can deliver a better experience to their already existing consumer base. Unique in the CDN landscape, we can label Comcast a B2C CDN service provider.
As the ISP, cable owner and CDN provider, Comcast is able to offer an excellent SLA and potentially lower pricing, when compared to 3rd party CDN providers who do not own the network they operate on.
The Comcast CDN is regional and offers PoPs within the US only. The CDN service is therefore not suited for businesses with a global userbase, unless it is combined with other CDN providers in a multi-CDN setup. Warpcache is a multi-CDN provider that offers the Comcast CDN in combination with others.
Comcast is a very suitable provider for a multi-CDN setup. Warpcache resells multiple providers, both in an integrated multi-CDN solution and separately.
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).
