Many years ago a brand new server room with its own dedicated HVAC systems being used for electronic home arrest nationwide started having all the machines fail each night every weekend. As you can imagine this was a panic mode situation and they had some of the sysadmins stay overnight. It turns out that the HVAC people despite knowing what it was used for, told the and having in fact been in the room setting up the underfloor programmed the A/C to shut off over the weekend to save electricity. When drama flows downhill from the Feds no-one is happy and the resulting meeting was almost as uncomfortable as the one after Qwest deliberately cut both sides of a fibre ring and then tried to sell us service. (We later found out Qwest's field people didn't want to cut a different carrier's fibre so they called back to confirm and were told to cut it or not come back in the morning.)
