From the wording above it seems you experienced some kind of "Murphy's 
catastrophe", like "A rodent somehow slipped in the server room and got 
fried after gnawing the mains cable and bringing the whole rack down". :-)

Just curious, could you explain in a bit more detail what happened? I 
was talking about catastrophic system failures to my students [1] last 
week and maybe this could make a nice case study? Of course feel free to 
ignore my request if you are too busy or if you cannot disclose the details.
