Years ago I had a registrar go tits up without warning, taking about 70-80 active domains for an MSP’s customers with it. I managed their email servers and DNS, which was with the registar, of course. It was a bloody nightmare to recover that situation. Because we couldn’t supply them a DNS change to prove our control of the DNS, hence ownership of the domain, we had to individually affadavit each domain. Took weeks.
I get you don’t think it’s important, but there’s plenty of sysadmins that do, with experience backing that up.
Well, our discussion didn’t go too far off the rails, but it sure escalated with the other commenter. I think this guy just likes to argue.
