Uptime is a measure of the 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 bigger than 100 days.
In contrast, planned downtime is downtime that occurs when an administrator shuts down the system at a scheduled time. Because planned downtime is scheduled, administrators can plan for it to occur at a time that least affects productivity. To remove or minimize planned downtime, you can implement server clustering. Even while performing maintenance on a primary node, server clustering provides continuous messaging availability for your organization (by means of temporarily failing over Exchange services to a standby computer in the Exchange cluster).
