There is no evidence that a global IT outage affecting airlines, banks, media and other business was caused by a cyberattack, France's cybersecurity agency said Friday.
"The teams are fully mobilised to identify and support the affected entities in France and to understand... the origin of this outage," the national cybersecurity agency (ANSSI) said, adding "There is no evidence to suggest that this outage is the result of a cyberattack."
A global tech outage was disrupting operations in multiple industries with airlines halting flights, some broadcasters off-air and everything from banking to healthcare hit by system problems.
American Airlines Delta Airlines, United Airlines and Allegiant Air grounded flights citing communication problems.
The order came shortly after Microsoft said it resolved its cloud services outage that impacted several low-cost carriers, though it was not immediately clear whether those were related.
"A third party software outage is impacting computer systems worldwide, including at United. While we work to restore those systems, we are holding all aircraft at their departure airports," United said in a statement. "Flights already airborne are continuing to their destinations."
