The following passage from the document contains multiple links embedded in the text: "On July 19, 2024, CrowdStrike, a U.S. cybersecurity firm, released a software update to their customers. The update caused certain systems to crash, disrupting services across several industries, including airlines, banks, hospitals, government agencies, and public safety systems. CrowdStrike reported that the incident was caused by 'a defect found in a single content update of its software on Microsoft Windows operating systems' and was not a cyberattack. Though the update affected less than 1% of all Windows machines, the impacts were widespread and global. The incident illustrates the vulnerabilities of information technology (IT) systems, increased dependence and risks in relying on third-party vendors for critical IT services, and lack of protocols and backup systems in the event of IT system failures. This In Focus discusses the incident's impact on certain U.S. public safety communications systems and services."
