Inktomi Corporation was an American Internet service provider (ISP) software developer based in Foster City, California. Customers included Microsoft, HotBot, Amazon.com, eBay, and Walmart.
The company developed Traffic Server, a proxy server web cache for World Wide Web traffic and on-demand streaming media which transcoded images down to a smaller size for users of dial-up Internet access. Traffic Server was deployed by several large ISPs including AOL.
In 2003, after the bursting of the dot-com bubble, the company was acquired by Yahoo! for $241 million.
The company's name, pronounced "INK-tuh-me", was derived from a Lakota legend about the trickster spider Iktomi, known for his ability to outsmart larger adversaries. The tri-color nested cube logo was created by Tom Lamar in 1996.
