Human error to blame for BA chaos: Report

London: A maintenance worker who inadvertently switched off the power to a key supply unit led to the British Airways chaos that disrupted the travel plans of over 75,000 passengers from the UK airports last weekend, a media report said today.
An internal email sent by Bill Francis, Head of Group IT at British Airways (BA) owner International Airlines Group (IAG), confirms that the shut-down had not been caused by IT failure or software issues, as claimed by workers union which blamed BAs outsourcing of IT jobs to India for the crisis.
The email reveals that an investigation had found that an Uninterruptible Power Supply (UPS) to a core data centre at Heathrow Airport was over-ridden on Saturday morning.

This resulted in the total immediate loss of power to the facility, bypassing the backup generators and batteries. This in turn meant that the controlled contingency migration to other facilities could not be applied," he writes.
"After a few minutes of this shutdown of power, it was turned back on in an unplanned and uncontrolled fashion, which created physical damage to the system, and significantly exacerbated the problem. This was entirely a problem relating to the power supply. It was not an IT failure, and there were no software issues," he adds.
The human error resulted in the eventual systems failure, which was working perfectly until it was accidentally shut down, according to a report in The Times.
"We are conducting an urgent investigation and it would be premature to comment on details before its conclusion. As weve said before it was not an IT issue, it was a power issue. There was no data corruption or loss and IT outsourcing was not a factor," the statement said.
