What caused the outage?
CrowdStrike president George Kurtz said the problem was caused by a “defect found in a single content update for Windows hosts”.
“CrowdStrike is actively working with customers impacted by a defect found in a single content update for Windows hosts. Mac and Linux hosts are not impacted. This is not a security incident or cyberattack. The issue has been identified, isolated and a fix has been deployed,” Kurtz said.
Key Background
Microsoft told Forbes Australia that the outage is impacting Windows machines. “We’re aware of an issue affecting Windows devices due to an update from a third-party software platform. We anticipate a resolution is forthcoming,” says a Microsoft spokesperson.
Australia’s National Cyber Security Coordinator (NCSC) acknowledged the technical issues and says the information it has indicates the outage is because of a third-party software platform. The NCSC states that there is no information to suggest a cyber security incident and that it is actively engaging with key stakeholders.
Prime Minister Anthony Albanese also made a statement, confirming that no triple-zero services have been impacted, and there has been no impact to critical infrastructure.
“I understand Australians are concerned about the outage that is unfolding globally and affecting a wide range of services,” Prime Minister Albanese stated. “My Government is working closely with the National Cyber Security Coordinator. The National Coordination Mechanism has been activated and is meeting now.”
