Frequently Asked Questions

Everything you need to know about API uptime, SLA calculations, and monitoring with Uptara.

SLA downtime is calculated by multiplying the downtime fraction (1 - SLA%) by the total number of seconds in a given time period. For example, a 99.9% SLA has a downtime fraction of 0.001. Over a 30-day month (2,592,000 seconds), 0.001 * 2,592,000 = 2,592 seconds (43 minutes and 12 seconds).
