How a restaurant should handle DNS TTL
11 Aug 2026
How a restaurant deals with DNS TTL — and what usually goes wrong.
The problem: TTL of 300 seconds. This is where DNS TTL breaks for a restaurant.
a restaurant asked us to look at DNS TTL after a customer screenshot showed a browser warning. The fix took eleven minutes; finding the cause took two hours.
We document DNS TTL in a shared spreadsheet. It is not glamorous, but a restaurant can open it on their phone at midnight if something breaks.
Fixing DNS TTL cost less than the lunch meeting where a restaurant decided to wait another quarter. Waiting is never free.
When we onboard a restaurant, the first thing we check is DNS TTL. It tells us more about the previous provider than any sales call.
Related work on this site follows the same principle: one job, a real inbox, no theatre. a restaurant did not need four analytics dashboards to know that Tuesdays are slow.
A static site for a restaurant does not need a CDN, a build pipeline, or a container. It needs correct DNS TTL and a host that stays online.
HTTPS is table stakes, but DNS TTL is where trust actually lives for a restaurant. A padlock with a misconfigured record behind it is decoration, not security.
