American Airlines and Delta ground ALL flights as 911 and hospital systems go down across the US after worldwide tech outage
Major US carriers American Airlines, United and Delta have grounded all flights as hospitals and 911 services reported systems outages amid what appears to be a global tech outage scuppering computers using Microsoft Windows.
Customers travelling with the carriers said on social media their pilots had told them all systems were down and that all aircraft must remain grounded until they are brought back online.
Many complained they had been left stranded in planes sitting on the tarmac before take-off or after landing at their destination, while images snapped in airports in the UK and Australia showed the departures terminals packed with travellers as flights were cancelled or delayed.
Social media was also awash with reports from medical staff that electronic medical record (EMR) systems had crashed, taking hospitals nationwide offline.
And images shared to social media showed self-checkout tills, ATM machines, television channels and a host of other tech displaying error messages.
Some of the outages appear linked to US IT company Crowdstrike and an update related to its ‘Falcon sensor’ – an agent that is designed to analyse internet connections to prevent viruses and other malicious software.
Several reports suggested the update caused a crash for computers running Microsoft’s Windows operating system.
‘Crowdstrike is aware of reports of crashes on Windows… related to the Falcon sensor,’ a prerecorded message says on the company’s helplines.
It was not immediately clear whether all reported outages were linked to Crowdstrike problems or there were other issues at play.
Windows is the most used operating system in the world, meaning the outage is affecting almost every part of the global economy.
