People went ballistic on me a few months ago for bringing this up, but this is exactly the kind of outage that makes me really, really worried about extremely short lived certificates. https://news.ycombinator.com/item?id=46118371
You know there’s more than one CA?
I'm not sure I follow. This outage seems like it occurred for less than 1 day. The post you link to is about having certificates expire after 45 days. What's the connection you see?
