A global IT failure related to the interaction between CrowdStrike antivirus and Windows is shaking the world's largest companies. It has caused problems in the operation of banks, airports, the London Stock Exchange, and more.
What is affected
- Windows operating system reports problems.
- Flights of several major US airlines, including Delta, United and American Airlines, Frontier Airlines, Allegiant, and Sun Country, were suspended due to communication problems.
- Turkish Airlines also suspended flights over a “major global outage”.
- Berlin-Brandenburg Airport in Berlin stopped working because of technical problems, as well as systems in the airports of Spain, Britain, Ireland, Australia, and other countries.
- The British SkyNews TV channel was disconnected due to a global outage.
- In Ukraine, the Nova Poshta delivery service was down, and Vodafone, Sense Bank, and Monobank had problems.
What's the reason
According to The Verge, thousands of Microsoft users around the world are experiencing a blue screen of death - a system message about a critical malfunction. Preliminarily, the failure was caused by an update of CrowdStrike, a cybersecurity software company.
Bloomberg also writes that banks and airlines around the world are operating intermittently after Microsoft reported the outage.
“Current status: We’re continuing to progress on our mitigation efforts for the affected Microsoft 365 apps and services. We still expect users to see remediation as we address residual impact. Scope of impact: This issue may be impacting any user attempting to use various Microsoft 365 apps and services,” Microsoft statement says.
Oleh Horokhovskyi, co-founder of Ukraine's Monobank, says that a global IT failure was caused by the interaction between CrowdStrike antivirus and Windows.
“Many companies are knocked down,” Horokhovskyi said.
