The short version
Key points
- Telstra identified three issues behind the 1 March Triple Zero outage: a database connection limit and software fault, incorrect backup numbers for some emergency operators, and a communication error affecting callbacks.
- A delayed emergency response in Melbourne was reported in connection with the outage, and a patient experiencing cardiac arrest later died.
- One million premises in both New South Wales and Victoria are eligible for fibre upgrades, although this does not mean one million premises in each state already have fibre connected to the home.
- Measuring Broadband Australia data showed improved peak-hour performance for higher-speed NBN services.
- Telstra’s Starlink plan was described as cheaper than the standard service, but with a 50 Mbps download cap and a minimum 10 Mbps upload speed.
Telstra’s Triple Zero outage had three separate causes
Telstra’s investigation into the 1 March outage found that it was not caused by a single failure. CEO Vicki Brady said the incident resulted from three issues occurring together.
The first was a technical fault that caused connections to a database to reach their maximum limit. This triggered a software fault that had not been detected. The resulting disruption affected several Telstra services, including mobile, internet and landline connections across Australia.
The second problem involved the backup process used for state emergency operators. Telstra stores backup phone numbers in a secondary database so calls can be transferred manually when required. For eight of the 24 hours on 1 March, the stored numbers for the 24 state emergency operators were incorrect, preventing those manual transfers from working as intended. The third issue was a communication error that delayed some callbacks from emergency service operators, particularly in Victoria. An updated email address supplied to the team was entered incorrectly into the system.
The outage had serious consequences
The incident received significant attention because of reported delays involving emergency calls. Victorian Ambulance Union secretary Danny Hill told ABC Radio Melbourne that a paramedic crew responding to a patient experiencing cardiac arrest was delayed. The patient later died, although the transcript does not establish that the outage was the sole cause of the death.
Reports also said some crews were dispatched without complete information. In some cases, details sent by email arrived after crews had reached the scene. Telstra apologised to people who attempted to call Triple Zero during the outage, including the family of the man who suffered the cardiac arrest.
Telstra committed to upgrading network infrastructure and improving monitoring and response capabilities. The investigation also identified weaknesses in the company’s redundancy systems, which are intended to limit the impact of network failures.
Fibre upgrade milestones in New South Wales and Victoria
NBN Co announced that one million premises in New South Wales and one million premises in Victoria were fibre-ready. This means the premises are eligible for an upgrade, rather than having fibre already connected inside every home. In the circumstances described, fibre is available nearby, often in a pit, and a connection may still require an appointment and installation work.
NBN data cited in the report showed that data consumption across both states had increased by more than 700 per cent over the previous 10 years. The average household was using 443 GB of data per month. Around 85,000 premises in each state had requested an upgrade from the eligible pool. Discussions about potentially doubling NBN speeds were still ongoing at the time of the video.
NBN performance and 6 GHz spectrum
The Measuring Broadband Australia report discussed in the video showed stronger peak-hour performance for higher-speed NBN services. Previously, peak-hour speeds ranged from 686 Mbps to 851 Mbps in September 2023. The newer range was reported as 818 Mbps to 851 Mbps. The change was linked to the removal of CVC charges on high-speed services under the updated Special Access Undertaking arrangements. The report did not indicate a comparable effect on lower-speed tiers, with only marginal gains for plans above 100 Mbps.
The ACMA was considering opening the 6 GHz spectrum band for unlicensed use, which could support technologies such as Wi-Fi 6 and Wi-Fi 7. The proposal was described as consistent with decisions made in other countries. Supporters said it could enable new wireless technologies, while the Australian Mobile Telecommunications Association raised concerns about interference with critical services and existing telecommunications infrastructure investments.
Telstra’s Starlink plans
Telstra announced plans to offer Starlink services, targeting regional locations that cannot access fast and reliable terrestrial services. The reported offer was $125 per month, compared with $139 per month for the standard Starlink service, with free hardware delivery also mentioned.
The main limitation was speed. Although Starlink can provide speeds above 200 Mbps on higher plans, Telstra’s offer was described as capped at 50 Mbps download, with a minimum upload speed of 10 Mbps.
TechManPat’s conclusion
I think the Triple Zero findings show how several smaller technical and operational failures can combine into a serious outage, particularly when backup and communication processes also fail. The NBN fibre milestones are encouraging, but eligibility is not the same as a completed home connection. I also see Telstra’s Starlink offer as having a significant speed limitation for a relatively small monthly saving.
