a network of mirrors accessible over HTTP or anonymous FTP, hosting software updates, sample code and various freely-downloadable utilities. Much of these sites were shut down in the first decades of the 21st century, with Apple shutting down its FTP services in 2012 and Microsoft stopping updates in 2010. Today, the contents of a number of these mirror sites are archived at The FTP Site Boneyard. Occasionally, some people will use web scraping software to produce static dumps of existing sites, such as the BBC's Top Gear and RedFlagDeals.
