I noticed in a dev commit some changes to warranty domain and cert notifications from 1, 7, 14, 30, and 90 to just 1, 7 and 45 days.
In my opinion the alert for certs should be 1, 7, 14 and 21 days. It's not really an actionable notification unless they aren't LE certs - and most are these days. But if I was alerted 3 weeks before it expires - ya that's probably something I need to action on and see why auto renew didn't work.
I admit, I don't know if 3 weeks would be enough time for all commercial certificate renewals. The other 2 alerts make sense at 45 days for sure.
