I have never seen the final root cause (actually direct cause, we know what the root cause was) report from Telehouse. Although I can understand why Telehouse wouldn't want to say what happened. Between replacing water pumps, reports of contanimation inside and outside the cooling system, fuel delivery delays, etc I'm not certain there was a single cause. From the outside there seemed to be multiple events, each with different direct causes. On Mon, 22 Jul 2002, Alex Rubenstein wrote:

The main generator for the 5th floor apparently ran for a while, but the radiator became clogged with garbage floating aroung in the air, and therefore couldn't cool itself, and overheated. They shut it down to prevent it from hurting itself.
Fuel was another issue.
