If this article is correct, then several questions have to be answered.
One is why had there not been a freeze on such work on one of the busiest periods of the year.
Another is why would an apparently competent person with a key shut down the power supply, which presumably was the UPS.
Any when it happened, why didn't the backup data centre at nearby Cranebank take over? I hope that one UPS isn't used for both data centres.
