Service uptime

Service uptime refers to the amount of time a service, system, or website is operational and accessible to users without interruptions. It is usually expressed as a percentage over a specific period, indicating reliability. For example, 99.9% uptime means the service is available almost all the time, with only a small amount of planned or unplanned downtime. High uptime is essential for ensuring consistent access and performance, especially for critical applications like financial services or online platforms. In essence, uptime measures how dependable a service is in providing uninterrupted access to users.
