Re: Errr.... Is that you Ross?
A little while ago, my boss and another long serving sysadmin were at our largest customer's office the other week, looking at installing some new core routers.
One of them leant on the rack, and somehow knocked out the power to the entire thing. Every single server and device in the rack went offline. Apparently it all went very quiet (and if you've done something similar, you'll remember that terrible silence, as if hundreds of fans had suddenly stopped).
It took them the rest of the morning to clean up the mess. We've not let him live it down yet :)
