dead link n.

[very common] A World-Wide-Web URL that no longer points to the information it was written to reach. Usually this happens because the document has been moved or deleted. Lots of dead links make a WWW page frustrating and useless and are the #1 sign of poor page maintainance. Compare dangling pointer, link rot.
