Common planning questions around uptime targets

Small percentage differences represent large chunks of time over a month or year. This calculator makes that tradeoff concrete.

Not exactly. Revenue is only one lens. Lost trust, support load, and operational distraction often make the real cost much higher.

Tighter uptime targets usually require faster detection, which means shorter check intervals and reliable alerting.
