Microsoft has announced that the underlying issue behind the disruption in its Azure cloud service has been resolved. The problem with Windows 365 personal computers was attributed to a recent update to CrowdStrike’s software.
CrowdStrike Holdings’ CEO, George Kurtz, also took to social media platform X to confirm that the company identified the update which caused the global crash in Windows systems, adding, “a fix has been deployed.”
“This is not a security incident or cyberattack,” Kurtz emphasised.
The disruption was traced back to CrowdStrike’s Falcon Sensor threat-monitoring software, which led to crashes in Microsoft’s Windows operating system. This, in turn, caused a global IT outage affecting Microsoft’s Azure cloud services, which disrupted numerous businesses worldwide.
Ajay Unni, CEO of cybersecurity firm StickmanCyber, commented to Reuters, “IT security tools are meant to ensure that they operate in the worst-case scenario. To be the root cause of a global IT outage is an unmitigated disaster.” Shares of CrowdStrike fell by nearly 20 per cent during pre-market trading on Wall Street this Friday, while Microsoft shares were also under pressure.
Microsoft Azure has reported successful recoveries from some customers attempting multiple virtual restart operations, though some ‘residual impact’ continues to affect certain Office 365 services.

Earlier today, IT Minister Ashwini Vaishnaw posted on social media platform X that the cyber protection agency CERT-In has released a technical advisory to resolve the issue, which disrupted several airlines’ operations and some stock broking services offered by private companies.
Ciaran Martin, Professor at Oxford University’s Blavatnik School of Government and former head of the UK National Cyber Security Centre, told Reuters, “This is a very, very uncomfortable illustration of the fragility of the world’s core Internet infrastructure.”
