The first one, I forget all the details but I think @Nick Sellors who's probably a lurker on this list, may give more details, but as I remember it...
Teledanmark (I think) had a PoP whose UPS needed upgrading. In preparation they topped up the diesel and fired up the backup generator, put the UPS into bypass and it was removed. The lorry carrying the new generator was reversing onto the site, and collided with the generator and took the site offline. The second one, and unfortunately my google-fu has failed to find the original text, is a story of how the night shift at a large computing facility would get bored and play cricket using a ball made of a rolled-up ball of paper and an improvised bat. The games got fiercer and the players better. Then one day someone hit the "ball" really hard for a perfect six and it hit the emergency power off. I seem to recall the author saying the sudden silence was shocking. The closest I could get to the story: https://www.usenix.org/legacy/publications/bibliography/byDate.html http://ftp.math.utah.edu/pub/tex/bib/usenix1990.html#Anonymous:1996:HSC
