Founded in 1997, Mirror Image Internet is a seasoned service provider with a large portfolio of web and hosting services. The company is principally owned by Xcelera Inc., and is headquartered in Massachusetts, US and has an European sales office in London.
The network map of Mirror Image is not made public on their website, and there is no information on the number of points-of-presence (PoPs). Based on performance comparisons, we think Mirror Image uses the Highwinds network, and add their own intelligence. Note that Mirror Image uses the term “Content Access Point (CAP) facilities” to refer to their PoPs.
Mirror Image Internet hold a variety of patents to protect its core technology. These concern Internet communication, web serving and the distributed selection of content servers.
The company offers features for video streaming and video-on-demand (VOD) through their miPUBLISHER platform. Large file download is also supported. Their control panel ClearVue Control Center includes real-time analytics and the necessary tooling to manage the CDN.
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 At the time of writing, the listings on the website seem out-of-date, as GameStop, Staples, Shutterstock, Yum!, L’Oreal and Pizza Hut no (longer) look to be customers of Instart Logic.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.
