A practical look at DNS TTL for a garage
29 Aug 2026
How a garage deals with DNS TTL — and what usually goes wrong.
The problem: a backup that was never restored as a drill. This is where DNS TTL breaks for a garage.
A static site for a garage does not need a CDN, a build pipeline, or a container. It needs correct DNS TTL and a host that stays online.
Email deliverability is nobody’s favourite topic, but a garage lost two bookings because DNS TTL was misconfigured and replies landed in spam for a week.
When we reviewed DNS TTL, the DNS panel showed a backup that was never restored as a drill. Two records contradicted each other, and the resolver picked one at random.
Managed hosting handles DNS TTL automatically — until it does not. a garage learned this when their provider migrated servers and a backup that was never restored as a drill disappeared silently.
After fixing DNS TTL, we added a monitoring alert. If the record changes or the certificate approaches expiry, both we and a garage get an email. No surprises.
We do not start with a platform when handling DNS TTL. We write down who types what, who gets the mail, and what must not get lost. That list is always shorter than a vendor pitch deck.
