This article is about uninterrupted system availability. For use in logistics, see Downtime. For enterprise computing, see high availability. For the first half of a double album by the Kleptones, see Uptime / Downtime § Uptime.
Uptime is a measure of system reliability, expressed as the percentage of time a machine, typically a computer, has been working and available. Uptime is the opposite of downtime.
Htop adds an exclamation mark when uptime is longer than 100 days.
It is often used as a measure of computer operating system reliability or stability, in that this time represents the time a computer can be left unattended without crashing or needing to be rebooted for administrative or maintenance purposes.
Conversely, long uptime may indicate negligence, because some critical updates can require reboots on some platforms.[1]
