Regarding the PerlGuru site that you mentioned (http://perlguru.com), it looks as if the site is currently misconfigured. According to the Wayback machine, it was live (and active) as recently as September 2018.

Unfortunately, the main page does not contain a direct contact link. There are references to the the hosting company.

In poking at the available links, it appears that the entire site was implemented as CGI calls. Because the site is misconfigured, none of the targets currently work. Other than the site's main page, archive.org doesn't seem to have captured much of the site's content (which is too bad as the site once had enough of a reputation to be included in some of the same lists as the Monastery, not to mention serving as another home for our very own japhy (according to rumor)).

Additional investigation turned up a contact name and an email address, but the underlying domain appears to have changed hands in 2008 and then allowed to expire. I was unable to find a more recent contact (or web presence) for the original owner or the business.

At this point, there appears to be little to do, unless someone happens to know the original owner or the webhost is interested in poking about enough to bring things back online.^[1]

^[1] - This might be a bit more work than simply fixing a driver error; the site does not appear to have had a proper SSL certificate when it was last captured.
