Global IT Outage Causes Chaos, Disrupting Airlines, Banks, Media, and Telecoms

Australia and European officials say no sign of cyberattack or security incident.

On Friday, July 19, 2024, a massive technology outage disrupted businesses and institutions in multiple countries, throwing airports, airlines, rail companies, government services, banks, stock exchanges, supermarkets, telecoms, health systems, and media outlets into chaos. The cause of the outage was not immediately clear, but it came hours after Microsoft said it was addressing an issue affecting access to Microsoft 365 apps and services. Australia and European officials have stated that there is no sign of a cyberattack or security incident.

Impact on Various Sectors

The outages rippled far and wide, with transport systems around the world among the hardest hit. Major airlines such as Delta, United, and American Airlines were grounded due to a communication issue, and flight information screens at Sydney airport went blank. Airports in the United Kingdom, Germany, India, Malaysia, the Philippines, and Spain reported disruptions to services. Additionally, banks and other financial institutions from Australia to India and South Africa warned clients about disruptions to their services. Media companies also saw their broadcasts severely disrupted, and government services were hit as well.

CrowdStrike's Involvement

Some experts attributed the disruption to CrowdStrike, a cybersecurity firm whose software is used by industries around the world to protect against hackers and outside breaches. The problem appeared to result in crashes of machines running the Microsoft Windows operating system. CrowdStrike reported that the issue was related to its Falcon sensor product, with engineers identifying a "content deployment problem".

Response and Recovery

At the time of reporting, some of the malfunctioning businesses, companies, and computer app systems were beginning to return to normal service. For example, Sky News in the United Kingdom, which was down for an hour in the morning, had resumed normal operations. However, the impact of the outage was widespread and affected various sectors for an extended period.

Official Statements

Australia's National Cyber Security Coordinator stated that the outage relates to a technical issue with a third-party software platform employed by affected companies, and there is no information to suggest it is a cyber security incident. Similarly, France's cybersecurity agency said there was no evidence that the global IT outage was the result of a cyberattack. A UK government security source also mentioned that the outage was not being treated as a malicious act.

Conclusion

In conclusion, the global IT outage had a significant impact on various sectors, causing disruptions in multiple countries. While the exact cause of the outage was not immediately clear, it is evident that the repercussions were widespread and affected critical services and systems across different industries.
