The Chief Financial Officer of Telstra has addressed the media regarding a nationwide outage that occurred on Wednesday. He explained that the disruption resulted from malfunctioning “nodes” responsible for time synchronization within several data centers of the network. Despite this information, Telstra has yet to determine the specific cause of the timer malfunction.
The outage has had a widespread impact, potentially affecting millions of Australians by disrupting payment systems and public transportation services. Updates on the situation can be tracked through Telstra’s live blog.
The incident began early Wednesday morning, with outage tracking website Downdetector.com recording a significant rise in complaints starting around 4:30 AM AEST. Reports surged from 308 to 776 within a brief window between 5:27 AM and 5:42 AM, reaching a peak at 6:42 AM when over 7,000 users reported issues with Telstra’s services. Although the volume of reports has since decreased, the most frequent problems reported were related to mobile signal (49%) and mobile internet (42%).
During a press conference, CFO Michael Ackland indicated that while he could not provide precise figures, he estimated that the outage affected thousands of Australians. He noted, “It could be tens of thousands, but I think it’s more likely in the thousands.” The disruption was not limited to any specific region, as customers from across the nation voiced their dissatisfaction. However, some customers reported on social media that they were still able to make calls, send texts, and access the internet without issues.
As for the underlying cause of the outage, Ackland stated that the definitive reason remains unknown. He speculated that the issues likely originated in the data centers located in Sydney and Melbourne, which are critical for synchronizing network systems and maintaining accurate time across Telstra’s entire mobile network. He explained, “You can imagine that many computer systems need to synchronize time. It’s essential for authenticating activities within the network. Unfortunately, the time synchronization in those nodes was not functioning properly, and we do not yet know why.” He added that while some nodes have been restored, it will take time for them to fully integrate back into the broader network, and further restoration efforts are ongoing.
Telstra has confirmed that there is no indication of a cyberattack or malicious interference, and the company is committed to investigating all potential causes of the outage. For customers experiencing issues, Telstra recommends several troubleshooting steps, including restarting devices and toggling airplane mode on and off.
In a statement released at approximately 10 AM AEST, Telstra reported that nearly 90% of calls and data services were once again functioning normally. Ackland emphasized that the immediate goal is to restore all services before addressing customer compensation, stating, “Our focus at the moment is absolutely on getting things up and running, and we will deal with our customers post the event.”
The ramifications of the outage have been extensive, affecting emergency calls, regional train services, and payment processing systems. While state police reported that the core Triple Zero (000) call centers were operational, some customers attempting to reach them experienced difficulties. Telstra is conducting welfare checks for users known to be unable to make emergency calls. Ackland reassured that the issue has not impacted Triple Zero in the same manner as other calls, although investigations into the matter continue.
Communications Minister Anika Wells confirmed that some emergency calls failed to connect earlier in the day. She stated, “The core Triple Zero system remains operational, with connected calls flowing as expected from carrier networks to the Emergency Call Person (ECP), and on to state and territory emergency services dispatchers. However, the Triple Zero Custodian has advised that some callers were unable to connect to the ECP, and these incidents are being investigated by Telstra.”
Additionally, commuters across three states have been significantly affected by the outage. In Victoria, the entire regional passenger rail network has been halted, with V/Line reporting that all services were suspended due to a radio network failure. While communication with the trains has been restored, CEO William Tieppo stated that operations will not resume until the network is deemed stable. Meanwhile, regional and some intercity train services in New South Wales are also experiencing considerable delays, with Transport for NSW reporting that routes between Sydney and Brisbane, Armidale, Casino, and Grafton have been impacted, while some services have been replaced by buses.
