Nasdaq Inc. is reviewing its systems to avoid a repeat of an hours-long shutdown in trading across the Nordic and Baltic markets, which prompted regulators to question its preparedness and forced Sweden to postpone a bond auction.
Trading went down Wednesday morning across the region and didn’t start up until shortly after 2 p.m. after an “errant fire extinguisher system” caused “connectivity issues” at a third-party data center in Vasby, a Stockholm suburb, according to Nasdaq.
