Why did Delta take days to restore normal service after CrowdStrike outage? Experts weigh in.
The delay was due to an IT failure that was difficult to fix, experts said.
An outage caused by a software update distributed by cybersecurity firm CrowdStrike triggered a wave of flight cancellations at several major U.S. airlines – but the disruption was most severe and prolonged at Delta Airlines.
In all, the carrier canceled more than 2,500 flights over a period that stretched from last Friday, when the outage began, into the middle of this week.
