Limelight Networks is an Arizona-based CDN provider that owns and operates its own content delivery network. The company was founded in 2001 and has offices in the US, Europe and Asia.
Limelight offers regular CDN services for static content, website acceleration, video streaming (Limelight Orchestrate) and cloud storage. Some of the services in the Limelight portfolio came to be from a variety of acquisitions done by the company in the past. Acquired companies include AcceloWeb (website acceleration), Kiptronic (video) and Delve Networks (video).
In 2006, the CDN provider was sued by Akamai Technologies, Massachusetts Institute of Technology (MIT) and later by Level3 over alleged patent infringements. In 2015, after a long string of decisions, came an end to the back-and-forth between Akamai and Limelight: Limelight was held liable for direct infringement of an Akamai-held patent by the US Court of Appeals for the Federal Circuit. In response to the ruling, Limelight Networks (NASDAQ:LLNW) fell greatly.
As of today, Limelight is still fighting a portion of the August 2015 decision, prolonging an already long-standing dispute against Akamai.
Limelight serves, or has served notable customers such as Disney, EA Sports, MySpace, Harpo Productions, MTV, Nintendo, Heineken and Carrefour. With the exception of the latter two, these customers are seemingly no longer with Limelight.
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.
