How do you manage references on a Wikipedia page when sources go offline?

Reference rot is a normal feature of any long-lived Wikipedia article: an article written years ago cites sources whose URLs have since moved, whose publishers have shut down, or whose paywalls have changed. Wikipedia’s response is procedural rather than manual, and it follows a clear sequence, detect the broken link, recover an archived copy, then propose the repaired citation through the Talk page.

The link-rot repair workflow

1. A dead-link bot flags the broken reference. Wikipedia runs automated dead-link detection that continuously checks articles and tags references whose URLs no longer resolve.
2. InternetArchiveBot retrieves an archived snapshot. Operated as a service of the Internet Archive in partnership with the Wikimedia community, InternetArchiveBot integrates with archive.org’s Wayback Machine to find an archived version of the dead URL and replace the broken link in the article’s wikitext with that archived copy.
3. A Talk-page edit request updates the citation. Where a bot cannot resolve it automatically, an editor can propose the updated citation through a Talk-page edit request, which an uninvolved community editor reviews against verifiability and reliable-sourcing policy before implementing.

A dead URL does not invalidate the source

Importantly, a broken URL does not on its own invalidate the underlying source for notability purposes, the source existed, the citation can be repaired, and the reference still counts. What does matter is accumulation: a sustained build-up of unrepaired broken references can erode an article’s perceived quality over time, which is why staying ahead of link rot is worthwhile maintenance.

How we treat it

For our work the workflow is to identify the broken references on a client’s article, recover current accessible or archived versions through archive.org (or by locating where the article moved to), and propose the citation updates through Talk-page edit requests rather than editing the article directly.
