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. The latter scenario is what happened on Wednesday night, as the sound produced by the releasing of the fire alarm's gas shut down around a third of the servers located in the Digiplex data center. Affected machines hosted services for Nasdaq Nordic, but also Finnish banks FIM Bank and OP Bank Group. Because of the incident, Nasdaq Nordic could not start trading operations at 08:00, local time, when stock markets across Northern Europe were set to open. Affected markets include the ones in Sweden, Finland, Denmark, Iceland, and the three Baltic states. Norway's Nasdaq operations were somehow not affected. Nasdaq Nordic fixed the issue by 14:00, local times, when it brought online a backup system to facilitate stock and securities trading in the area. Nasdaq officials told Finnish media the backup system will remain in use until Monday when they'll be able to replace affected equipment. A Digiplex spokesperson told Bleeping Computer that Nasdaq only rents space in the data center, and uses its own equipment. Nasdaq said there weren't enough servers in the whole of Sweden to replace the destroyed ones, and had to import new machines. "Airplanes are just coming down," Lauri Rosendahl, President of Nasdaq Nordiq, told Finnish newspaper Helsingin Sanomat today. Digiplex is one of the largest data centers in the area, with hundreds of servers housed in a 20,000 sqm (215,000 sqft) building in Väsby, near Stockholm, Sweden. This is not the first time a loud noise caused by a fire alarm system has shut down a data center. In September 2016, a similar incident shut down the data center of ING Bank Romania for ten hours.
