Meltdowns Hobble NSA Data Center - WSJ.com

Meltdowns Hobble NSA Data Center - WSJ.com:
There have been 10 meltdowns in the past 13 months that have prevented the NSA from using computers at its new Utah data-storage center, slated to be the spy agency's largest, according to project documents reviewed by The Wall Street Journal.

10 meltdowns are a lot and it is going to increase the spending, I suspect.
A couple of weeks later, on Sept. 23, the contractors reported they had uncovered the "root cause" of the electrical failures, citing a "consensus" among 30 investigators, which didn't include government officials. Their proposed solution was the same device they had already begun installing.
The Army Corps of Engineer's Tiger Team said the contractor's explanations were unproven. The causes of the incidents "are not yet sufficiently understood to ensure that [the NSA] can expect to avoid these incidents in the future," their report said.
So, a problem almost every engineer faces sometime during his career: root cause analysis. What is root cause? How to prevent the same or similar failures to happen again? How to measure the effectiveness of the prevention measures?
