A loud sound emitted by a fire alarm system has destroyed the hard drives of a Swedish data center, downing Nasdaq operations across Northern Europe.
The incident took place in the early hours of Wednesday, April 19, and was caused by a gas-based fire alarm system that are typically deployed in data centers because of their ability to put out fires without destroying non-burnt equipment.
These systems work by releasing inert gas at high speeds, a mechanism usually accompanied by a loud whistle-like sound. With non-calibrated systems, this sound can get very loud, a big no-no in data centers, where loud sounds are known to affect performance, shut down, or even destroy hard drives.

One way to reduce the risk is to move all the hard drives out of the data center and use 'the cloud.' As data connections get faster, the performance hit will be less and less. If it's still an issue, move the processors, too. Actually, once the data centers are empty of computer hardware, leaving only empty racks, power usage will go way down and the risk of fire all but disappears. Finally, the room can be pre-flooded with fire suppressant gas to eliminate the (small) residual risk of fire.
