Except when they do go down. Not as a result of the processor itself, but as a result of the hiccups in the dependency chain.

In one case ours went down for a day when a backhoe hired for construction cut a power supply line. The data center batteries designed to give time for the desiel generator to kick-in were fine. The generator failed to start as a result of contaminated fuel despite monthly tests.

The second time was when an employee brought their 12 year old son into the raised floor environment. He found and pressed the haylon dump button for fire suppression. Staff were lucky to escape without suffocation.

The employee was fired and stricter entry requirements to the raised floor area were implemented.
