CacheFly is a service of CacheNetworks, LLC, based in Chicago, IL. CacheFly launched in 1999 as Downloadhosting.com, a download service for small software developers. In 2005, the CacheFly CDN was launched. It was one of the first to use IP Anycast routing, which minimized latency by directing user requests to the topologically nearest edge server. It branded this method of content delivery as BestHop. Revenue was estimated at $27 million in 2011. CDN edge locations include 10 in the US, 11 in Europe and the Middle East, and 8 in Asia and Oceania. Key differentiators include the use of Anycast instead of DNS for optimized content delivery, a large global Anycast network, near real-time access to CDN logs, and a number of high-profile customers, including Bank of America, Honda and Microsoft.
