As first reported by , a gas-based fire alarm system frequently used in data centers went off at Digiplex in the early morning of April 19, 2018. The loud whistle that accompanied the release of the gas caused around a third of the servers to shut down. According to the report, the shutdown affected Finnish banks and Nasdaq Nordic, which operates its own devices at the data center. That morning the company was unable to begin trading in parts of northern Europe and was forced to import new servers, due to a lack of them in Sweden.

A similar incident took place in 2016: Back then, reported a server failure at a data center at the Romanian subsidiary of ING Bank. While testing the fire alarm system, a loud bang from the gas cartridges caused the damage, which took ten hours to repair. "Hard disks respond badly to vibrations," reports Oliver Nickel at . The fire alarm in Sweden likely caused the magnetic disks to vibrate so strongly that they were destroyed. Any movement could damage the highly compact technology – even movement generated by sound waves. Late last year, issued a warning based on a US study that attackers could take advantage of this.
