Microsoft Cloud Disruption Hits Airlines, Banks, Media & More

A major IT outage linked to a Microsoft security issue has caused widespread disruptions across the globe, affecting banks, airlines, media organizations, and numerous companies. This Friday morning, a widespread outage disrupted access to Microsoft 365 apps and services. The root cause is believed to be linked to a CrowdStrike security software update that impacted Microsoft cloud services. The issue quickly escalated, affecting a range of critical systems and services globally.

The Chain Reaction

The outage began with a significant problem affecting Microsoft 365 apps and services. The initial reports indicated that the issue stemmed from a recent update to CrowdStrike's security software, which inadvertently impacted Microsoft’s cloud infrastructure. Israel’s Cyber Directorate and an X user report suggest that CrowdStrike’s Falcon Sensor platform may have triggered the disruption. While CrowdStrike and Microsoft have not officially confirmed this, the connection between CrowdStrike's software and the outage is a critical point of investigation.

The outage was first reported by DownDetector, which tracks user-reported internet outages. It affected major corporations like Visa, ADT Security, and Amazon, as well as airlines such as American Airlines and Delta. News outlets in Australia reported that telecommunications providers, banks, and media broadcasters were also disrupted. In the U.K., Europe, and India, airlines and banks reported similar issues, with some New Zealand banks going offline.

Microsoft’s Response

Microsoft acknowledged the issue, stating on X (formerly Twitter) that they were "working on rerouting the impacted traffic to alternate systems to alleviate impact in a more expedient fashion" and that they were "observing a positive trend in service availability." However, the company did not provide further details about the cause of the outage or respond to requests for comment.

Global Impact

In New Zealand, acting Prime Minister David Seymour emphasized the need for rapid understanding of the potential impacts. He noted that there were no indications of malicious cyber activity but acknowledged the significant inconvenience for the public and businesses.

In Israel, the Cyber Directorate attributed the outage to issues with the cybersecurity platform CrowdStrike. This disruption affected the country's post offices and hospitals. Similar issues were reported in South Africa, with Capitec Bank customers unable to make payments.

1. Airline Disruptions

Airline operations faced severe disruptions globally. In the U.S., major airlines like United, American, Delta, and Allegiant were grounded. Passengers at Los Angeles International Airport were seen sleeping on the jetway floor due to delayed flights. In the U.K., Ryanair and train operators reported disruptions, advising passengers to arrive early due to the global IT outage.

2. Airport Challenges

Airports in Australia, India, Hong Kong, Germany, and Switzerland reported significant delays and disruptions. Melbourne passengers faced long queues as online check-in services were disabled. Hong Kong’s Airport Authority and Amsterdam’s Schiphol Airport both switched to manual check-in processes. Berlin and Zurich airports experienced similar issues, affecting flight operations and causing delays.

3. Healthcare and Media Impact

The healthcare sector was also hit, with hospitals in Britain and Germany reporting issues. In England, several National Health Service practices were unable to access patient records, impacting appointment bookings and information provision. In Germany, the Schleswig-Holstein University Hospital had to cancel elective surgeries but continued to provide emergency care.

News outlets worldwide, including Australia’s ABC and Sky News, reported outages that led to sudden broadcast interruptions. Media groups faced significant operational difficulties as Windows-based systems crashed.

4. Banks and Financial Services

In New Zealand, banks such as ASB and Kiwibank reported service outages. Similarly, Australian banks including NAB, Commonwealth, and Bendigo faced interruptions. Capitec Bank in South Africa also experienced nationwide service disruptions, affecting customers' ability to make payments.

Looking Ahead

As organizations and governments scramble to assess and manage the fallout from this massive IT outage, questions about data recovery and long-term impacts remain. The incident highlights vulnerabilities in critical infrastructure and the interconnectedness of modern technology systems.

The situation continues to evolve, with ongoing efforts to restore services and prevent further disruptions. For many, the recovery plan and data security measures will be key to mitigating the long-term consequences of this significant global event.
