Is there a non-opiniated evaluation/assessment/study of why a long system uptime is something which is worth to achieve?

Pro:

  • Long uptime - stable system
  • Linux system does not necessarily need a reboot on updates

Contra:

  • Fast pacing changes require approaches like dynamic infrastructures and frequent updates
  • After long time (years) do you really know you could restore (reinstall) such system from a disaster?

As observed today:

  • A quite old RedHat system with an uptime for half a year
  • Changes in the networking environment have an ambigous effect that some packages go through, some not
  • After reboot, works

You fell victim to the Goodhart's law:

When a measure becomes a target, it ceases to be a good measure.

High uptime is not the goal - availability is. And availability is achieved with a combination of uptime and redundancy.
