Right. Probably because the churn on custom names would mean recreating the certificate several times a day. > I’ll port it over to netlify which works.

As a courtesy you could notify the operators of the DNS you are leaving, if that's not built into your control panel functions. > In practice, if it isn’t straightforward (“If I [expletive] it up”), I > don’t want to break someone’s production run at 15:00 on Friday > afternoon, so I’ll wait until the weekend.

There's no problem in relying on the Internet so long as you have a Plan B. Relying exclusively on a single point of failure is, of course, a recipe for unwanted occurrences :-) P --------------------------------------------------------------------- To unsubscribe, e-mail: docbook-unsubscr...@lists.oasis-open.org For additional commands, e-mail: docbook-h...@lists.oasis-open.org
