Root Cause Analysis:

Production Server outage caused by field tech misreading instructions.
Instructions indicated: “Check serial numbers on Data Center servers. Do not touch.”
Tech’s interpretation: “Unrack all equipment, stack in corner, and go to lunch”
Management is pushing for clearer instructions in attempt to mitigate risk of this happening in the future.
