Soon after the shaking stops, I go to the pitch-black, silent server room with a flashlight, and push the Big Red Button, expecting to cut off power and clean up the mess when we return to work.
A few days later I return to a big surprise ...
All the servers were running.
Emergency Power Off buttons need power to cut off power.
We had already lost power due to the earthquake, so pushing the Big Red Button did nothing.
Remember that for next time!
