On Friday, a global cyber outage caused by a software update led to widespread disruptions, grounding flights, suspending certain broadcasters, and affecting services from banking to healthcare
Microsoft’s (MSFT.O) Windows Operating System users were affected by an update to a product offered by global cybersecurity firm CrowdStrike (CRWD.O), which opened a new tab. Microsoft announced that the issue had been resolved later on Friday.
On the social media platform X, CrowdStrike CEO George Kurtz announced that the company was “actively working with customers impacted by a defect found in a single content update for Windows hosts” and that a fix was being deployed.
“This is not a cyberattack or security incident,” Kurtz stated in the post.
On Friday morning, flights were suspended by major U.S. airlines, including American Airlines (AAL.O), Delta Airlines (DAL.N), and United Airlines (UAL.O). Additionally, delays and disruptions were reported by carriers and airports worldwide.
Traders across markets reported difficulties with transaction execution, while banks and financial services companies from Australia to India and Germany warned customers about potential disruptions.
“We are experiencing the most severe global market disruptions,” stated a trader.
In Britain, medical officials posted multiple reports on X indicating that the booking systems used by doctors were offline. Sky News, one of the country’s major news broadcasters, was off-air and apologized for its inability to transmit live. Manchester United, a soccer club, announced on X that it had to postpone a scheduled ticket release.
Amid an ongoing global outage, Azure, Microsoft’s cloud unit, acknowledged the issue that affected virtual machines running Windows O.S. and the CrowdStrike Falcon agent becoming trapped in a “restarting state.”
“We are cognizant of an issue affecting Windows devices as a result of an update from a third-party software platform.” A spokesperson for Microsoft stated, “We are confident that a resolution will be forthcoming.”
CrowdStrike issued an alert to clients on Friday at 0530 GMT, informing them that its “Falcon Sensor” software was causing Microsoft Windows to malfunction and display a blue screen colloquially referred to as the “Blue Screen of Death.” Additionally, it disclosed a manual solution to resolve the matter.

Ciaran Martin, former head of the U.K. National Cyber U.K.curity Centre and Professor at Oxford University’s Blavatnik School of Government, stated, “This is a very, very uncomfortable illustration of the fragility of the world’s core Internet infrastructure.”
The effects of the disruptions were widespread.
The disruption necessitated the manual check-in of passengers by certain airlines at airports in Singapore, Hong Kong, and India.
Iberia, an airline, reported that it had been operating manually at airports until its electronic check-in counters and online check-ins were reactivated. In contrast, Amsterdam’s Schiphol Airport, one of Europe’s busiest airports, was also impacted. It indicated that there had been some delays but no flight cancellations.
Air France-KLM (AIRF.PA) reported that its operations were disrupted in a new tab.
The Dutch foreign affairs ministry informed the Dutch press agency ANP that it had been impacted. A spokesperson was not readily accessible for comment.
Despite reports of companies progressively restoring their services, analysts scrutinized the potential of what one termed the “largest-ever outage” in the industry and the broader economy.
Ajay Unni, CEO of StickmanCyber, one of Australia’s largest cybersecurity services companies, stated, “I.T. security I.T.ols are all designed to ensure that companies can continue to operate in the worst-case scenario of a data breach. Therefore, to be the root cause of a global I.T. outage is an unmitigated disaster.”
