SSL Certificate Expiry and How to Stay Ahead
An expired certificate looks like a full outage. Here is how to make sure it never catches you.
A predictable, avoidable outage
When a certificate expires, browsers block the site with a warning that looks like a security breach. The service is fine, but no one can use it. And the expiry date was known all along.
Automate, then verify
Automatic renewal is the right default, but renewal hooks break after config changes and fail without telling you. Automate it, then independently confirm the certificate actually renewed.
Do not forget the edges
The certificates that lapse are usually the forgotten ones on an old subdomain, an internal tool, or an API endpoint. Inventory every certificate you depend on, not just the main site.
Warn with room to act
Track each certificate's expiry and get reminded well before the date. A couple of weeks of warning lets you fix a broken renewal calmly instead of during an incident.
