A very long time ago I worked for a medium sized company and there was a power outage. The servers were in a room in our building but they had ups power. The problem was that the ups's were broken/malfunctioning and the servers needed to do a disk check after an unplanned reboot. It took hours before we could work again even though most drives survived. This was also before git so we could not reach the central version control system and could not commit any code. I think all code and workspaces were on servers that was not up yet.
