Wikipedia Community and Internet Archive Partner To Fix One Million Broken Links on Wikipedia (wikimedia.org)
More than one million formerly broken links in the English Wikipedia have been updated to archived versions from the Wayback Machine, thanks to a partnership between the Internet Archive, and volunteers from the Wikipedia community, and the Wikimedia Foundation. From a blog post: The Internet Archive, the Wikimedia Foundation, and volunteers from the Wikipedia community have now fixed more than one million broken outbound web links on English Wikipedia. This has been done by the Internet Archive's monitoring for all new, and edited, outbound links from English Wikipedia for three years and archiving them soon after changes are made to articles. This combined with the other web archiving projects, means that as pages on the Web become inaccessible, links to archived versions in the Internet Archive's Wayback Machine can take their place. This has now been done for the English Wikipedia and more than one million links are now pointing to preserved copies of missing web content. What do you do when good web links go bad? If you are a volunteer editor on Wikipedia, you start by writing software to examine every outbound link in English Wikipedia to make sure it is still available via the "live web." If, for whatever reason, it is no longer good (e.g. if it returns a "404" error code or "Page Not Found") you check to see if an archived copy of the page is available via the Internet Archive's Wayback Machine. If it is, you instruct your software to edit the Wikipedia page to point to the archived version, taking care to let users of the link know they will be visiting a version via the Wayback Machine.

I have found many cases on Wikipedia where the links are broken but the correct content exists at a different URL. This auto-archive system would bypass that and perhaps prevent ever recognizing that the link target still exists. This is especially an issue for links to corporate and government pages where someone periodically gets the bright idea to reshuffle the web site's organization and doesn't put in permanent redirects.
Because the Internet Archive applies robots.txt rules retroactively.
