A simple checklist before leaving a small server alone

Small servers usually fail in ordinary ways: an expired certificate, a full disk, a forgotten firewall rule, or a service that never restarted after a package update.

Before leaving one unattended, I like to confirm the basics: automatic certificate renewal, a clear list of listening ports, a working backup path, and a restart policy for the main services.

The last step is the easiest to skip: write down how to recover access. A tiny note with the hostname, user, key location, and emergency console link can save a long evening later.
