Yes It was in The Times today.

Quite ridiculous. The contractor must have stopped the feed from the UPS system to the processor and storage modules. That should simply not be possible.

Turning off the mains supply to the UPS system would not have had any effect for a considerable time, during which alarms would have been going off all over the place.

Or should have been.

an electrical engineer disconnected the uninterruptible power supply which shut down BA's data centre.
This resulted in the total immediate loss of power to the facility, bypassing the backup generators and batteries... After a few minutes of this shutdown, it was turned back on in an unplanned and uncontrolled fashion, which created physical damage to the systems and significantly exacerbated the problem."

So you can have the best systems in the world.....

But you can not legislate for stupid humans

But was it the best system in the world ? dont sound like it to me.

Didn't say it was.... Only said you CAN have... But nothing can stop someone who should know better.

Fair point..

Back in my early days as a design engineer I was told that it's not too hard to make something foolproof... if you try really hard you might even be able to make it idiot-proof.

But you can't make it proof against a determined idiot

Confirming my suggestion .

Well it certainly should not have caused a crash at another data centre or at any connected locations.

That resilience is available. It just wasn't built into the system.
