Re: Smells funny.
An oil company and I can't spill the name (it wasn't BP though) had a power outage at one of their DC leading to an outage at that DC. In the post mortem it was discovered that the UPS had worked fine but the first generator had developed a fault or already had a fault. The second generator had conked out just after starting up and the third had lasted about 15 mins before ceasing to work. The reason for the second and third generators failing was that no one had checked the fuel tanks.
