Homelab Hero · No. 009

One incident. Three calls.

Sunday, 6:05 PM. The VM that runs your home DNS fails to boot after an update: every device joins the Wi-Fi happily, and nothing can resolve a single name. Dinner guests arrive in an hour. On the shelf: a spare Pi and last month's backup of your DNS config.

Your call:

A. Point the router straight at a public resolver and call it fixed for the night

B. Start the spare Pi on the backed-up DNS config, point the router at it as primary with a public resolver second, and fix the VM after the guests leave

C. Roll back the VM snapshot and keep debugging it while the house stays offline
