Starting next year:
> Our longstanding offering won’t fundamentally change next year, but we are
> going to introduce a new offering that’s a big shift from anything we’ve done
> before—short-lived certificates. Specifically, certificates with a lifetime of
> six days. This is a big upgrade for the security of the TLS ecosystem because
> it minimizes exposure time during a key compromise event.
>
> Because we’ve done so much to encourage automation over the past decade, most
> of our subscribers aren’t going to have to do much in order to switch to
> shorter lived certificates. We, on the other hand, are going to have to think
> about the possibility that we will need to issue 20x as many certificates as
> we do now. It’s not inconceivable that at some point in our next decade we may
> need to be prepared to issue 100,000,000 certificates per day...
