Hello. If you are interested in managing dead links I've found some info that might be useful: * There is a MediaWiki library, DeadlinkChecker [1], in PHP that checks if a link is dead or alive. * There is also a library for WikiMedia wikis in python, Pywikibot [2], which has a script that finds dead links: weblinkchecker.py [3]. * There is an extension, RottenLinks [4], that can list all external links and their status, it would tell which ones are broken. * Finally, there is a bot, IABot [5], in PHP. It looks very complete and manages dead links. I don't have experience developing web backend, but I could try to help in what I can.
