Monitoring a new storefront through every market launch.
Specialist retailer, several European markets
- Checkly
- Sentry
The challenge
A specialist retailer was moving to a new Shopify storefront one European market at a time. Each launch needed close watching, but checking every market at full speed would have needed more than three times the browser runs in its monitoring plan.
What we built
81 checks in five layers, from “is it up?” to “can I shop?”: availability, certificates and DNS, stock, prices and search, and real-browser shopping journeys. Sentry shows what real visitors run into: errors, failed requests and page speed, per market. The market that is launching gets checked fast, settled markets move to a slower schedule, and alerts go to the team’s chat.
The result
At the first review, 100% availability across the live markets that week, and three gaps found and closed: error tracking had gone silent for four days when its quota ran out, nothing was watching certificates or DNS (24 monitors added at no extra cost), and the team’s own visits were being counted as customer traffic.
