The CrowdStrike outage that started late on Thursday is still causing havoc as Delta was forced to scrap an additional 1,250 flights yesterday on top of the 3,500 already cancelled, Reuters reported. That has left tens of thousands of Delta fliers stranded waiting for new flights that could take days, forcing many to cancel or postpone trips. The airline has yet to say when it will resume normal operations.
Delta has scratched a third of scheduled flights for a total of 5,000 since Friday, and delayed another 1,700. “In particular one of our crew tracking-related tools was affected and unable to effectively process the unprecedented number of changes triggered by the system shutdown,” said Delta CEO Ed Bastian.
CrowdStrike’s software update affected 8.5 million Windows devices, causing many to go into a boot loop that could only be recovered by technicians with direct access to machines. The problem turned out to be a faulty sensor designed to detect malicious activity that “triggered a logic error that resulted in an operating system crash,” according to CrowdStrike.
Delta was the worst hit of any US airline, and United Airlines was a distant second with about 266 (9 percent) of flights cancelled on Sunday.
At first, United and Delta told stranded travelers that they wouldn’t cover bills since the CrowdStrike crash was out of their control. However, US Transportation Secretary Pete Buttigieg later stepped in and said that he considered the situation self-inflicted, so carriers would need to cover food, transportation and lodging costs for any delays longer than three hours as required by law.
CrowdStrike said today that a “significant” number of devices are back online and the company is reportedly close to rolling out an automatic fix to the issue. Also heavily impacted by the outage are healthcare and other public services in the US and UK, with the NHS warning patients that “there may still be some delays.”
