The malfunction in US air traffic control equipment will not be resolved soon, Homeland Security Secretary Markwayne Mullin told reporters.
According to him, at present, it is almost impossible to estimate the timetable for the potential restoration of air services. Mullin noted that the priority is to ensure that planes in the air can land safely. He added that he had no clear information about how long this situation might last.
Mullin also emphasized that the outage was not caused by a failure of Microsoft services, although he added that there may be a connection. He also noted that US President Donald Trump had been briefed on the incident.
