Uptime/SLA calculator: what is an SLA and how to calculate it?
A Service Level Agreement (SLA) is a document that details the expected level of service guaranteed by a vendor or product. This document generally sets out metrics such as uptime expectations and any payoffs if these levels are not met. For example, if a provider advertises an uptime of 99.9% and exceeds 43 minutes and 50 seconds of service downtime, technically the SLA has been breached and the customer may be entitled to some type of remuneration depending on the agreement.
