Then if your CA went down for an hour, you would go down too. With 47 days, there's plenty of time for the CA to fix the outage and issue you a new cert before your current one expires.

Lots of ACME software supports configuring CA fallbacks, so even if a CA is down hard for an extended period you can issue certificates with the others.

Using LetsEncrypt and ZeroSSL together is a popular approach. If you need a stronger guarantee of uptime, reach for the paid options.

If everyone uses that with 1 minute or 1 second expirations, I could certainly see a case where an outage in 1 CA causes traffic migration to another, causing performance issues on the fallback CA too.

We don't. If we had 1 minute or 1 second lifetimes, we would.

Oh, agreed. I was responding to the part about extended outages.
