alt Hacker NewsIs that actually true, though? Even though it's not really my job, I find myself debugging certificates and keys at least once a month, and that's after automating as much as possible with certbot and cloud certificates. PKI always seems to demand attention.
In my initial comment, I meant more in terms of complexity and planning from the perspective of the people who are running the public/private key infrastructure on the other side/upstream of what you're doing as a letsencrypt end user.
Broadly similar general concept to the team responsible for the DNSSSEC signing keys for an entire ccTLD.
Yeah a x509 PKI / root CA is a very different thing than DNSSSEC but they have a number of general logical similarities in that the chain of trust ultimately comes down to a "do not fuck this up" single point of failure.
