Cobalt Networks Inc.
Cobalt Networks Inc. was a maker of low-cost Linux-based servers. Founded in 1996 in Mountain View, California under the name Cobalt Microserver, the company pioneered easy-to-use server appliances featuring secure web user interfaces, designed for Internet service providers (ISPs) and small to medium sized businesses. In December 2000, Sun acquired Cobalt but due to the internet bubble soon after the acquisition, the ISP market shrank dramatically. In December 2003 Sun retired all Cobalt products, making the underlying software and firmware open source.
The dedicated server market was one of the largest customer markets for Cobalt servers. Cobalt Networks produced many different types of appliance servers. The two most popular were the Cobalt RaQ3 and RaQ4 and although the product line was cancelled by Sun, Cobalt's products had lasting impact.
