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 At the time of writing, the listings on the website seem out-of-date, as GameStop, Staples, Shutterstock, Yum!, L’Oreal and Pizza Hut no (longer) look to be customers of Instart Logic.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.
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.
