- To request URL changes WP:Link rot/URL change requests
|This page in a nutshell: Steps may be taken to reduce or repair dead external links.|
Like most large websites, Wikipedia suffers from the phenomenon known as link rot, where external links go dead (also called a dead link), as the linked websites disappear, change their content, or move. This presents a significant threat to Wikipedia's reliability policy and its source citation guideline.
In general, do not delete cited information solely because the URL to the source does not work any longer. Tools, procedures and processes are available as outlined in this document.
