Commonwealth Bank (CommBank) experienced a major technology outage on October 1, 2025, which disrupted online banking services, the mobile app, and ATMs nationwide in Australia. This outage lasted for about an hour, during which many customers were unable to access their accounts, make payments, or withdraw cash from ATMs. The bank has since fixed the technical issues and restored all services by the afternoon of October 1, 2025, apologizing for the inconvenience caused to customers.
