The past year at ISRG has been a great one and I couldn’t be more proud of our staff, community, funders, and other partners that made it happen. Let’s Encrypt continues to thrive, serving more websites around the world than ever before with excellent security and stability. Our understanding of what it will take to make more privacy-preserving metrics more mainstream via our Divvi Up project is evolving in important ways.
compromising a keypair is a huge win. lets you impersonate the domain. shorter validation periods = smaller windows of compromised situations.
basically the smaller you make the window the less manual intervention and the less complicated infrastructure gets. currently TLS systems need a way to invalidate certificates. get them down to a day and suddenly that need just disappears. vastly simplifying the code and the system. 6 days is a huge improvement over 90 days.

Ok, I slid right by the “compromised” word. Makes sense now.
you mean you slid right on by an understanding of how security infrastructure works. since one always assumes credentials will be compromised.
