Once in the data center where the company i worked had their equipment, a car crashed in the outside wall, and was just the place where 1 of the two whole floor power panel were, so half of the equipment crashed due to lack of energy, and also broke a fibre patchpanel, so the available bandwidth was minuscule. And in other ocasion, one repair gang in the city literally cutted a fibre cable with a street digger, and the repair lasted about 1 month. Massive catastrophic failure due to external causes IS a possible scenario. And yes, it IS a world class data-center. ===== Miguel Ruiz Velasco Version: OpenKeyServer v1.2 Comment: Extracted from belgium.keyserver.net Signature: 0x59831109 __________________________________ Do you Yahoo!?
