CROWDSTRIKE'S IMPACT ON AVIATION

Summary from the TLDR Web Dev newsletter

CrowdStrike's software update on July 19th caused a massive IT outage that impacted air traffic, particularly for major airlines like Delta, United, and American, which experienced widespread cancellations. While Southwest remained largely unaffected, Delta faced the most severe consequences due to its reliance on Windows systems and a lack of effective disaster recovery plans. Despite widespread disruptions, the impact of the outage was systematically analyzed using ADS-B Exchange data to compare takeoff rates before, during, and after the update, providing insights into the scale and duration of the disruption.
