Chaos ensued. Every department relies on that server to update all they do. On POETS day, they try to go earlier -4.30 and when the "system says no" they run, with wild eyes, foaming at the mouth to THE "IT bod" in the office. Which is me.
No words of re-assurance and comfort work. I am the devil. I managed to get full restoration of the server, minus a few last minute updates, by 5.10.
This made me late for my Young's so I ain't happy.
