that the C10k problem was tractable on contemporary systems. Due to a mirror licensing dispute situation with Coast to Coast Telecommunications in 1995 (now Allegiance Telecom, part of XO Communications), archive maintainer Keith Petersen left his employment with CCT and moved on to Walnut Creek CDROM. In October 1999, Digital River purchased Simtel from Walnut Creek CDROM for US$1.0 million and 143,885 shares of common stock. Mr. Petersen contracted with Digital River, along with small business owner and son Kurt Petersen of Petersen Business Management, to manage the Simtel collections and continued to do so until January 15, 2001. The service was shut down on March 15, 2013. Some mirrors may still be available. References External links File hosting Internet properties established in 1993
