Could you elabrate more regarding "broken"? Are they all top leve
sites or some of them were sub sites and could not find any links from
the top level sites?

Have you tried to create links to one of these sites and try to open
it?

Sure. They are all top-level sites. In the site  Directory > Sites
List, each site is that isn't working is assigned "broken" for the
Link Status Column. I attempted following the given links and
creating links to where the site shoulda been, but recieved a 404
error the webpage cannot be found.
