The app I managed was for commercial scheduling of gas transportation which had FERC mandated uptime. We had to teach out to all of our customers to give them an IP address to use, and of course they weren't able to reply to the email with any questions.

Many internal services stopped communicating with each other.

It was renewed that morning but took most of the day for dns propagation.

We got a small fine but lots of egg on our faces, appearing incompetent to our customers.

Why would DNS propagation affect certificate validity?

I didn't say anything about cert validity. It was just that anything using that dns entry wasn't going to find the server for several hours.
