Overview
- A widespread outage that began in the early hours on Wednesday left thousands of Telstra customers with lost calls and mobile data and triggered a surge of reports on outage trackers.
- Telstra identified malfunctioning time‑synchronisation nodes in some data‑centre servers as the proximate fault, but the company and regulators say the ultimate root cause remains under active investigation.
- The failure caused cascading problems for critical services, halting Victoria’s regional V/Line network, disrupting some regional NSW services, affecting EFTPOS terminals, some EV chargers and traffic and ticketing systems.
- Some Telstra users could not reach the Triple‑Zero emergency number, prompting Telstra to conduct hundreds of welfare checks and refer dozens of unreachable callers to police for follow up.
- By late Wednesday most services had been restored, Telstra and the government report no evidence of malicious activity so far, and ministers, ACMA and consumer groups are pressing for enforceable reliability standards and possible compensation.
