CNN —A major US health care system said Thursday that it is diverting ambulances from “several” of its hospitals following a cyberattack this week. The sprawling health care network, which also owns 40 senior living facilities, said that it would be using “downtime procedure for some time,” because of the cyberattack. It was not clear how many Ascension hospitals were sending ambulances to other locations because of the cyberattack. It’s only the latest major hacking incident that has hobbled a big US health care network and sent US officials scrambling to offer support. A February ransomware attack on Change Healthcare, a subsidiary of health care giant UnitedHealth Group, caused billing disruptions at pharmacies across the US and threatened to put some health providers out of business.
