Not sure if they still do it, but in the video I shared they clearly 
demonstrate a tech replacing a unit (kind of, he put a unit in where a 
slot blocker was, but they didn't say whether that was previously empty 
or was from a pulled unit).  I have doubts that they try to fix all (or 
any of) those bad, pulled units, but I bet to try and take maximum 
advantage of the cooling and switching expenses per container they do 
swap them out in chunks, maybe when some threshold is hit on a container 
(10 or more machines dead or some such thing).

Best,
