Opinion: Who will pay for the Crowdstrike outage?

While some other airlines including United have had mass flight cancellations since the outage – which stemmed from security updates related to Microsoft 365 apps and services from cybersecurity firm CrowdStrike – Delta has had far more flight cancellations than any other US airline. — John Spink/The Atlanta Journal-Constitution/TNS

Crowdstrike did not have a good day on July 19. During a routine software update, the file that the cybersecurity firm issued triggered a logic error that prohibited Windows machines from rebooting. Microsoft estimates that around 8.5 million computers may have been affected by the event.

This created a tsunami of downstream consequences, as computers that supported numerous industry operations were unable to coordinate and process data.
