Overview
- Optus says a technical fault during a firewall-related network upgrade early Thursday blocked triple-zero calls in South Australia, Western Australia and the Northern Territory.
- About 600 customers were potentially affected, and welfare checks later linked four deaths to failed attempts to reach emergency services, including an eight-week-old boy and a 68-year-old woman in South Australia.
- Authorities now say the disruption lasted around 10 hours, far longer than initially indicated, and WA’s St John Ambulance said it was not briefed by Optus during the incident.
- CEO Stephen Rue acknowledged the company lacked alarms to detect the failure and that early complaints were not escalated, saying access was restored about 1:50pm Thursday and promising daily updates and full cooperation.
- Federal and state investigations are being set up, ACMA oversight is expected, and coronial examinations will consider the circumstances, with substantial penalties possible given Optus’s prior emergency-call breaches.
