Telstra CEO Apologizes After Server Error Disrupts National Services

Telstra executives testified before a Senate inquiry in Canberra on July 17 and 18, 2026, regarding a nationwide mobile outage on July 8. Vicki Brady, the chief executive, apologized for the failure, stating the company let Australians down and conceded that internal controls were insufficient.

The outage began at the Exhibition Street exchange in Melbourne, where a technician replaced a chassis housing a network timing server. Upon power restoration, a faulty GPS card caused the server to reset its date to 2006. This erroneous timing information propagated across the network, invalidating authentication certificates and disconnecting customers. At its peak, the failure impacted 45 percent of calls and data sessions, disabling triple-zero emergency services and disrupting regional train networks in Victoria and New South Wales, as well as EFTPOS systems for approximately 80,000 businesses.

Testimony revealed the failure stemmed from an undocumented intentional design change and a missing software update. US-based supplier Microchip Technology had warned Telstra about a rollover problem in November 2020 and January 2026, but the company failed to apply the fix. Greens Senator Sarah Hanson-Young characterized the incident as incompetence and called for stronger consumer protection rules.

Telstra has conducted over 630 welfare checks for affected emergency callers and is accepting compensation claims. The Australian Communications and Media Authority is currently investigating the company's network maintenance and customer notification processes.
