I clicked the lookup button, and got an HTTP 500. Should I start by restarting the server? The instructor reads command output, configuration, and logs from a local Linux VM and containers alongside the audience on screen, then methodically walks through processes and configuration, DNS, proxies and TLS, containers, CI/CD and rolling deployments, permissions, observability, and backups and restores. Rather than relying on a restart to see if things recover, they establish criteria for deciding whether to proceed, stop, or roll back by separating what the records have confirmed from what still needs to be checked.
