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.
Instart Logic is a CDN provider founded in 2010, and is headquartered in Palo Alto, California. The company is known for its $100 million contract buyout campaign targeted at Akamai customers.
Customers in the Instart Logic portfolio include, or have included: Quora, Washington Post, and Kongregate. At the time of writing, the listings on the website seem out-of-date, as GameStop, Staples, Shutterstock, Yum!, L’Oreal and Pizza Hut no (longer) look to be customers of Instart Logic. At least not for static file delivery.
Through a partnership with ChinaCache, Instart Logic offers coverage of mainland China with points of presence (PoPs) in roughly 140 cities.
Instart Logic supports SPDY.
