This strategy is from the Large Hadron Collider project:
Improvements in performance per Watt have caused CERN to no longer sign hardware support contracts longer than three years. Machines run until they die. They have a very high utilization of equipment (‘duty cycle’, 7 x 24 x 365). Replacing hardware makes more sense because of the lower cost and the power savings of new hardware.
