There is a false belief that a physical server is some kind of “iron rock” that should run for years without a single stop. The owner’s logic is understandable: plenty of resources, no noisy neighbors on shared hosting, the system feels stable. Yet in real operation, an uptime of several years usually points not to reliability, but to the absence of critical security updates in memory. A scheduled restart is not a fix for a problem, but a routine procedure that helps avoid performance degradation and hidden vulnerabilities.
