On July 19, a significant IT outage caused widespread disruptions across various critical sectors globally. This incident, which originated from a flawed software update, affected countless businesses, hospitals, airlines, and financial institutions, highlighting the vulnerabilities inherent in our interconnected technological infrastructure.
The Cause of the Outage
The root of the problem was identified as a faulty update issued by CrowdStrike, a leading American cybersecurity firm. CrowdStrike’s systems, which are designed to protect users from cyber threats, inadvertently triggered a malfunction. The company’s software, specifically the CrowdStrike Falcon product, caused issues on machines running Microsoft operating systems. As a result, vital services, including login systems and information displays, went dark, creating chaos for businesses and customers alike.
In addition to the CrowdStrike-related issues, there was an earlier outage involving Microsoft’s Azure cloud services. Some users faced compounded problems due to both incidents.
Despite CrowdStrike’s quick response and the release of a fix, many systems required manual updates to restore functionality. George Kurtz, CrowdStrike’s CEO, acknowledged the severity of the situation and indicated that full recovery would take time.
The Impact Across Sectors

The outage had a widespread impact, affecting multiple sectors and regions. In Australia, Sydney airport experienced long delays as information screens went blank. Similar issues occurred at airports in the UK, Germany, Taiwan, and South Korea, where manual processes like handwritten boarding passes had to be employed.
The situation was particularly dire in the healthcare sector. In Germany, some hospitals had to cancel elective procedures, while in the UK, doctors in the National Health Service struggled to access critical systems. In the United States, Kaiser Permanente activated backup systems to continue patient care. Emergency services were also hit, with 911 lines in multiple states experiencing issues.
Financial institutions were not spared either. Banks like JPMorgan Chase faced delays in processing trades, while TD Bank customers reported difficulties accessing online accounts. However, some organizations, such as the London Stock Exchange and the Norwegian central bank, managed to continue operations without significant disruptions.
Response and Recovery:

The global nature of the outage meant that the recovery process varied by region and sector. In Ukraine, companies like Sense Bank and Vodafone reported only brief disruptions. Dubai International Airport managed to resume operations swiftly by switching to alternative systems. However, the cascading effects of the outage meant that some U.S. airports continued to experience delays well into the day following the incident.
CrowdStrike took full responsibility for the issue, with CEO George Kurtz publicly apologizing and assuring customers that the incident was not a cyberattack. Kurtz emphasized that the company’s systems were still protecting users from potential threats. Meanwhile, Microsoft provided guidance to affected users, suggesting multiple system reboots and, for those with advanced technical knowledge, specific file deletions.
