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).
CacheFly is a Chicago-based CDN provider, with over 40 Points of Presence (PoPs) spread over six continents. Next to the usual locations, Cachefly has PoPs in India, Qatar, Egypt and South Africa.
The Cachefly network is optimised for throughput, making it more suitable for the delivery of large files.
Instead of DNS-based global loadbalancing, the company’s CDN infrastructure relies on TCP Anycast routing.
CacheFly offers the usual features in the CDN industry such as instant purge, origin shielding, real-time reporting and sub-accounts. They also offer a 100% availability SLA and 24⁄7 support.
