Go to a grad office and talk to PhD students in technical subjects (other than CS). Ask them, what is a certificate, DNS, reverse proxy, SSH public key, docker, TCP/IP, hypervisor, … You would be surprised how many people have no idea! You can’t expect people manage their servers.

I spent half of today tracking down a DNS issue at home. Your home lab will evolve and there will be changes. You need to stay current with the required knowledge, and that takes time and attention.
