Articles with dead links

What the name says. Such links should be repaired (if dead because of a typo) or replaced (if the page has gone 404) as soon as possible. Ideally, this category should be empty most of the time, like the Candidates for deletion category.

To flag a dead link, put {‍{dead link|date the link was flagged as dead}} beside it. Kindly do not use any all-numeric format for the date, except International as this is the only unambiguous one.
