Comments from people asking for or offering mirrors of inaccessible articles are very frequent. Old articles disappear from the web, leaving discussions that lack context. HN should offer a link to a cached version in the header of the item page.

While it would be easiest to use an external service and just add the link, I think HN should consider creating its own archive of all submitted articles. The articles, links, commentary, and voting data could one day be a great corpus for future scholars (and current-day CS researchers).
