A global software outage triggered by a faulty CrowdStrike cybersecurity update has caused widespread disruptions to air travel and other critical services for four consecutive days. The issue, which affected 8.5 million Windows devices, has impacted airports, hospitals, emergency services, and government agencies.Delta Air Lines has been the most severely affected airline, canceling over 5,300 flights since Friday, July 19. As of Monday, July 22, Delta had canceled an additional 700 flights, representing 19% of its daily operations. The airline’s CEO, Ed Bastian, explained that the outage affected Delta’s crew tracking system, making it unable to process the high number of changes triggered by the system shutdown.Other major U.S. airlines, including American Airlines and United Airlines, have largely recovered from the initial disruptions. However, Delta’s continued struggles are partly attributed to its hub-and-spoke flight model, which concentrates flights and crews in a few major hubs, making the airline more reliant on automation.The scale of the disruption is significant, with FlightAware reporting a total of 11,600 flights canceled and 115,185 flights delayed across all airlines since the outage began. Delta is offering compensation to affected passengers, including travel waivers, vouchers, and SkyMiles. However, Transportation Secretary Pete Buttigieg has criticized the airline’s response, demanding prompt refunds and reimbursements for customers who had to cancel their trips.CrowdStrike, the cybersecurity company responsible for the faulty update, has apologized for the inconvenience and is working to resolve the issue. Microsoft has published a recovery tool to help address the problem. The incident has raised concerns about cybersecurity practices and the potential vulnerabilities in critical infrastructure systems.
