99.9999% uptime

99.9999% uptime means a service is available and operational almost all the time—specifically, it can be down for only about 3.65 seconds per year. This extremely high reliability minimizes disruptions, ensuring consistent access for users. It’s a standard often used for critical systems where downtime can have significant consequences, such as financial services or healthcare infrastructure. Achieving this level of uptime involves robust infrastructure, redundant systems, and proactive maintenance, all aimed at delivering uninterrupted service with minimal interruptions.
