Alaska Communications Systems is "endangering the health and safety" of thousands of Fairbanks residents by failing to provide updated phone numbers for the city's "Enhanced 911" system, the Fairbanks North Star Borough has charged in a lawsuit. "As a result, borough citizens face an impending disaster -- a 911 call for help from someone in distress who is not able to verbally communicate," the borough charged in its Aug. 25 complaint in state court.
