The 2:14am server failure nobody noticed
situation
Their order system ran on a single database server — the classic setup. It had been "fine for years," which is what every single point of failure says right up until it isn't.
what we built
- Replaced the lone server with a clustered setup: if one machine fails, a standby takes over automatically
- Spread the cluster across two locations so even a site problem doesn't stop orders
- Added monitoring that pages our on-call engineer the moment anything looks off
- Rehearsed the failure on purpose, repeatedly, until the recovery was boring
result
Months later, the main server died at 2:14am — real hardware failure, not a drill. The standby took over in 4.2 seconds. No orders lost, no late-night calls, no morning crisis. The client read about it in our incident note over coffee.
- recovery time
- 4.2 seconds, automatic
- orders lost
