Situation
There was one final task before leaving for dinner: shut down the local desktop workstation and walk away. The workstation and the production server were both open side-by-side in terminal windows on the same 3440×1440 ultrawide monitor.
The desktop workstation on the left and the remote production server on the right intentionally shared the same Sway desktop and terminal appearance. Both terminals were visible at the same time.
What Happened
The shutdown command was entered without noticing that the active terminal was not the intended one. The command completed, and the session appeared to be finished.
Only after standing up to leave for dinner did something feel unusual: the desktop computer was still running.
That short moment of confusion identified the mistake. The active terminal had been connected to the remote production server, Worldnode, rather than the local workstation, Cthulhu. The production server had shut down exactly as instructed.
Solution
The provider console was used to reconnect and start the server again. The website and every World Observer service were then checked and confirmed to be back online.
Lesson
The command wasn't wrong.
The terminal was.
