BERLIN, NOVEMBER 15 /SRNA/ - A service outage at U.S. technology giant Microsoft caused chlorine poisoning among 15 people at a swimming pool in an amusement park in the western German city of Brühl, German broadcaster WDR reported.
According to WDR, the outage affecting Microsoft's Outlook service prevented emails from coming through, and no one noticed that the monitoring system had already sent an email alert warning that the concentration of the substance had exceeded safe levels.
In essence, the automatic dosing system released an excessive amount of chlorine into the pool.
According to the broadcaster, the pool water was replaced following the incident, and the facility has since reopened to visitors.
The Bild newspaper reported yesterday that around 15 people had suffered chlorine poisoning at the park's swimming pool and that some had sought hospital treatment.
