Telstra chief executive Vicki Brady has publicly apologised for the national outage on Wednesday that disrupted mobile services, Eftpos, rail operations, and some triple zero calls for nearly five hours. Speaking in Sydney on Friday, Brady expressed deep regret for the impact on customers and the community.
Outage Cause and Known Risks
The outage was triggered by a software fault in Telstra's time-telling systems, which erroneously reset the network to November 2006. This caused a cascading failure that brought down services within minutes. Brady acknowledged that timing systems are critical in mobile networks and that the company was aware of the risks. She admitted that backup systems failed to prevent the outage, and an investigation is underway to determine why.
The ABC reported that Telstra had been warned by the government's Cyber and Infrastructure Security Centre about the critical nature of its time-keeping services. Similar incidents have occurred elsewhere, such as a 2020 outage in Jersey where a time server generated the wrong date, leading to a five-day service disruption.
Government and Regulatory Response
Communications Minister Anika Wells stated that it is now "time for Telstra to face the music" and that the company has many questions to answer. The Australian Communications and Media Authority (ACMA) will investigate the outage. Telstra could face civil penalties of up to $30 million if found in breach of legal obligations under powers strengthened after the Optus triple zero outage.
South Australian police ruled out a link between the outage and a reported death. Police Commissioner Grant Stevens confirmed that triple zero calls were successfully made in the incident, and there was no record of a failed call from a Telstra phone. However, Telstra later acknowledged that intermittent voice and data issues prevented family members from being informed about the hospitalisation of their loved one, apologising for the added distress.
Telstra's Response and Next Steps
Brady cut short an overseas trip to address the public. She said the company is cooperating with authorities and investigating why redundancy measures failed. Chief financial officer Michael Ackland confirmed that there were no active outages in the local area at the time of the reported death, but the company is reviewing any connection to the outage.
The outage has sparked criticism of Telstra's infrastructure resilience. Wells criticised the opposition for politicising the event, including shadow minister Sarah Henderson testing triple zero herself. The ACMA investigation will examine compliance with regulations, and Telstra may face significant penalties if found negligent.
