why is commbank down

The Commonwealth Bank (CommBank) experienced a major technology outage on October 1, 2025, that affected online banking services, mobile app access, payments, and ATMs across Australia. This technical failure caused customers to be locked out of their accounts, with reports of ATMs shutting down and inability to complete transactions like grocery purchases. The bank issued an apology and worked urgently to fix the issue, which lasted for about an hour before services began restoration. By the afternoon of October 2, 2025, CommBank confirmed that all services were restored and normal operations resumed.
