Context
An agency managing dozens of client websites found out about outages the worst way — from the client. (Placeholder case study — real copy lands in phase 2.)
Problem
No single view of which sites were up, slow, or visually broken after a deploy.
Solution
A checker that probes every site on a schedule, stores screenshots in S3-compatible storage for visual verification, and alerts the team on failures.
Outcome
Placeholder metric: 100+ sites monitored; average time-to-detection down from hours to under two minutes.
