Question for the panel: is it better to just leave the links as is (with a note that the site does not exist anymore), remove them altogether, or replace the links with archive.org links?
See WP:DEADREF; see also [[Wikipedia:Dead external links]].
Linking to an archiving service, marking the dead link with the {{dead link}} template, or even finding an alternative reference, are all preferable options to simply removing the reference.
Convenience links (links to online copies of offline material) are naturally a different kettle of fish; they are merely supplementary to the offline reference.
