It'd be really fascinating to compare that with WHOIS data for the domains. That might show other misissuances - certificates issued for non-registered domains.
It looks like an expected long tail, most of them were probably issued only days or weeks after the codes used should have expired (in 2017).
What made this one jump out was the use of a 1024-bit RSA key. When it was really ordered that would be completely normal, but even in 2017 it would have been obviously prohibited, I have looked at a few of the other 112 and they're unextraordinary, typically 2048-bit RSA keys, likely originally ordered earlier in 2017.
It would be useful (perhaps I will ask on m.d.s.policy) to know what the actual original order dates were for the 112 certificates in this list.
