How a garage deals with lastmod dates — and what usually goes wrong.

The problem: a calendar they already pay for. This breaks lastmod dates for a garage.

We moved lastmod dates for a garage to a provider that supports DNSSEC. It added five minutes to the migration and closed a class of attacks they did not even know about.

Fixing lastmod dates cost less than the lunch meeting where a garage decided to wait another quarter. Waiting is never free.

WordPress can handle lastmod dates with a plugin. But the plugin adds JavaScript, a dashboard, and a support ticket when it conflicts with the next update. We wrote four lines of config instead.

a garage did not need a portal. They needed a page that said who they are, what they do, and a phone number that somebody picks up before the fifth ring.

The vendor portal had silently rotated the key for lastmod dates, but a garage was still using the old one. Every outbound message bounced quietly.

Crawlers and people want the same thing from lastmod dates: one URL, a title that matches the heading, and a next link that goes somewhere real.
