A global outage of Microsoft’s Windows software has caused significant disruptions across various essential services worldwide, including airports, supermarkets, and banking services. The timing of the outage is unclear, but reports began flooding in early Friday, with airlines among the first to notice issues.
Users attempting to log into their systems encountered the “Blue Screen of Death (BSoD),” indicating system errors and prolonged inaccessibility, which typically resolves quickly but persisted this time.
The source of the problem was initially suspected to be an internal Microsoft issue but was later traced back to a cybersecurity firm, CrowdStrike. The company admitted that a bug in its content update for Microsoft caused the widespread outage.
CrowdStrike’s CEO, George Kurtz, assured the public that the issue was purely technical and not a cybersecurity threat. Consequently, CrowdStrike’s shares plummeted by 15%, wiping out $12.5 billion of its market value. Notably, Mac and Linux systems were unaffected by this problem.

Global Microsoft Windows Outage Disrupts Essential Services; CrowdStrike Bug to Blame
The outage had severe consequences, particularly for the aviation industry, where around 1,400 flights were canceled globally. Major airlines like Delta, Turkish Airlines, and Qantas faced cancellations and delays. Airports in various countries, including the UK, Switzerland, Japan, and India, experienced significant disruptions, with passengers stranded and flights grounded.
Besides the aviation sector, supermarkets in the UK struggled with card payments, and hospitals and pharmacies faced challenges accessing patient records and staff rosters.
In response, CrowdStrike issued an apology and assured that efforts were underway to resolve the issue. Microsoft confirmed that the underlying problem had been fixed, but residual impacts continued to affect services. Experts warned that full recovery could take days, although there were signs of improvement, as reported by DownDetector, indicating that services like Visa and XBOX were gradually stabilizing.
This outage highlights the world’s heavy reliance on Microsoft and the need for better contingency plans. It underscored the necessity for Microsoft to implement robust backup systems to mitigate the effects of such widespread disruptions.
The incident serves as a crucial reminder of the vulnerabilities in our digital infrastructure and the importance of diversifying our technological dependencies to prevent similar future occurrences.
