In an unprecedented turn of events, financial services, medical offices, and television broadcasters worldwide faced severe disruptions on Friday due to a significant IT outage. Air travel was particularly affected, with numerous flights grounded, services delayed, and airports scrambling to advise passengers.
The root cause? A faulty software update by cybersecurity giant CrowdStrike, highlighting a striking irony: the greatest cybersecurity issue in history wasn’t a cyberattack but a technological mishap.
The chaos began early Friday when CrowdStrike reported a major disruption following an issue with its latest tech update. This incident quickly escalated, impacting a wide array of sectors globally.

The U.S. National Security Council, aware of the incident, said it is investigating its implications.
German Chancellor Olaf Scholz, currently in Belgrade, stated that German security institutions are working with international partners to resolve the IT outage affecting air travel, banking, and various companies.
CrowdStrike CEO George Kurtz said that the issue was neither a security incident nor a cyberattack.
“This is not a security incident or cyberattack. The issue has been identified, isolated, and a fix has been deployed,” he stated on social media.
Despite the fix, the damage was already extensive, causing widespread disruptions.
The Widespread Impacts
The effects of the IT outage were felt worldwide. Passengers at New York’s John F. Kennedy International Airport faced significant delays as part of the global IT outage. The Federal Aviation Administration reported that several airlines requested assistance with ground stops for their fleets until the issues were resolved.
While American Airlines, Delta Air Lines, and United Airlines resumed some flights, they warned of ongoing delays and issued waivers for customers to change their travel plans.
In South Africa, two major banks, Capitec and Absa Group, reported temporary service disruptions due to the global outage.
Capitec informed customers of nationwide service disruptions caused by an “unexpected issue with an international service provider.” After several hours, both banks announced the restoration of their services.
In the healthcare sector, Britain’s Royal Surrey Hospital in Guildford declared a “critical incident” due to external IT issues affecting its services, particularly the IT system used for radiotherapy treatments. While the hospital managed to deliver radiotherapy services, it had to reschedule appointments, with disruptions potentially extending into the following week.
Cybersecurity researcher Troy Hunt described the ongoing global tech disruption as “the largest IT outage in history.”
The CrowdStrike outage caused cascading failures across multiple industries, including airlines issuing ground stops, broadcast networks going off-air, and critical services scrambling to mitigate the impact.
Satnam Narang, senior staff researcher at cybersecurity firm Tenable, noted the profound impact of the outage, describing it as unprecedented.
“It’s very far-reaching, and we’re still just at the beginning of this right now,” Narang told CNBC.
He explained that security software, due to its privileged access to machines, played a critical role in the failures.
“People may see these as Windows failures with a little blue screen popping up, but it’s related to a faulty or bad update from the security software,” he said.
The Challenge of A Solution
Tom Lysemose Hansen, Chief Technology Officer at Norwegian cybersecurity company Promon, noted that resolving the global IT outage might not be straightforward.
“CrowdStrike’s affected customers will have to effectively break into their own systems to get everything back online by logging into the admin console and booting their systems in safe mode,” he explained.
CrowdStrike’s software is deeply integrated into the operations of many organizations, from point-of-sale systems to ATMs and Microsoft Windows systems.
CrowdStrike CEO George Kurtz has apologized for the disruption caused by the systems update. Kurtz reiterated that it was not a security incident or cyberattack and assured that the company was working diligently with customers to restore services.
“The system was sent an update, and that update had a software bug in it, causing an issue with the Microsoft operating system,” he told NBC’s “Today.”
The Irony and Lessons
While the tech world remains vigilant against external threats, cybersecurity experts note that this incident serves as a potent reminder of the vulnerabilities that can arise from within. The greatest cybersecurity issue in history, ironically, was not the result of a malicious cyberattack but a software update gone wrong, impacting millions and offering valuable lessons for the future of IT and cybersecurity.
Analysts attribute the incident to the interconnectedness of modern IT infrastructure, where a single point of failure in a critical service provider’s software can cascade into widespread disruptions across multiple sectors and countries.
As businesses and services worldwide work to recover from this unprecedented outage, experts advise that the focus should shift to understanding the root cause of the issue and implementing measures to prevent a recurrence.
For CrowdStrike, the immediate priority is restoring trust and ensuring that its systems and processes are scrutinized to prevent future incidents, they say.
