Setting up SPF for a garage
17 Sep 2025
How a garage deals with SPF — and what usually goes wrong.
The problem: a certificate that expires on a Sunday. The SPF check fails for a garage.
If the hours on Google disagree with the site, people trust Google and then arrive angry. SPF will not fix that. The hours page will.
We moved SPF 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.
The most expensive outage for a garage was not a hack — it was a certificate that expires on a Sunday. Nobody attacked anything. The config just drifted.
The hosting bill for a garage is twelve dollars a month. Their old provider charged eighty and included a page builder nobody used. SPF was broken on both plans.
We once forgot to renew SPF for a weekend project and it took down a page that a garage linked to from a print flyer. We now set auto-renew on everything.
