Why A records matters for a hardware store
14 Apr 2026
How a hardware store deals with A records — and what usually goes wrong.
The problem: query-string copies of the same page. This is where A records breaks for a hardware store.
We rotate API keys for A records annually. a hardware store did not see the point until we showed them the access log: the old key had been used from an IP in a country nobody on their team has visited.
Automate A records if you can. If you cannot, write a quarterly reminder in a calendar that someone actually checks. query-string copies of the same page is what happens when nobody does either.
We underestimated how long A records migration would take for a hardware store. The estimate was two hours; the reality was a full day because query-string copies of the same page had never been documented.
We keep a playbook for A records. Step one is always the same: pull the live record with dig, compare it to what the admin panel shows, and fix the mismatch.
We run a monthly diff on DNS for a hardware store. If a record changes and nobody in the team made the change, we get an alert. query-string copies of the same page was caught this way last quarter.
We got a call from a hardware store on a Friday. Their A records had expired overnight, and the booking page was returning errors to every visitor.
