SSL Certificate Health Check Automation

We had lost LMS access before because a certificate quietly expired and nobody was watching for it. For a platform that customers and partners log into, an expired cert is not a small ops hiccup, it is a trust problem, the kind that makes people wonder what else is being missed.

The real issue was that the plan was remember to check the cert, which is not a plan. Certificate expiry is exactly the sort of slow, silent deadline that human attention is bad at and automation is good at.
