Delta Airlines has expressed frustration with CrowdStrike in a new letter on Thursday, as the two companies continue to trade jabs after last month’s massive global network outage.
The BBC is reporting that the US-based carrier accused the cybersecurity company of “negligence”, saying it was forced to cancel thousands of flights because of the outage and had lost at least US $500 million as a result.
CrowdStrike had denied it was solely responsible for Delta’s flight disruptions, which it said continued after other carriers came back online.
Delta has since been hit by a class-action lawsuit filed on behalf of affected passengers.
The global glitch originated from CrowdStrike on July 19, after it had sent out a corrupted software update to its huge number of customers.
Microsoft estimated that 8.5 million Windows devices around the world were disabled as a result.
