Optus Firewall Enhancement Results in Triple Zero Disruption
Firewall Misconfiguration: The Core Issue
Optus CEO Stephen Rue confirmed that a standard firewall enhancement at 12.30am resulted in a 13-hour failure of Triple Zero calls. The problem was linked to a misconfiguration of the firewall, which wasn’t identified by their telemetry systems. Rue mentioned that while typical call volumes remained unaffected, the monitoring of emergency calls was not included in the system checks.
Delayed Reaction: Need for Enhancements
The telecommunications company became aware of the problem only after customer reports emerged, and it took 13 hours for Optus to fully grasp the extent of the outage. After receiving customer feedback, Optus reverted the firewall updates and reinstated services. Rue acknowledged that the management of initial reports fell short of expectations, and the delay in escalating these reports represented a major oversight.
Government Response and Responsibility
Federal communications minister Anika Wells criticized Optus for the sluggish notification process, highlighting that both federal and state governments were alerted late. She stressed the necessity for Optus to investigate why alarms and testing mechanisms failed to identify the outage swiftly. Optus has accepted full accountability and is initiating an internal review, while external probes by ACMA and other entities are expected.
Future Outlook: Preventative Strategies
In light of the incident, Optus plans to designate an independent monitor to analyze the outage and guarantee that similar problems are avoided in the future. The telecommunications company also seeks to act on recommendations from the prior 2023 incident to enhance communication for public and emergency services during outages.

Optus endured a major interruption of its Triple Zero service due to a misconfigured firewall during a standard upgrade. The company’s slow response and absence of prompt communication have attracted criticism from government officials.
