Telstra's CEO told a Senate inquiry that a neglected software update on a critical timekeeping system caused last week's nationwide network outage. Maintenance staff were unaware of the design change and the mass outage risk it posed.

The Australian telecommunications giant blamed the incident on a failure to update key infrastructure that controls network timing. The problem 'rippled slowly across the network,' according to CEO Vicki Brady's testimony. The outage highlighted a breakdown in internal processes. Maintenance teams did not know about a design modification that affected how the system would reset during failures, leaving them unprepared when the critical failure occurred. Telstra's network serves millions of Australians. The outage disrupted emergency services, banking, and communications across the country for several hours last week. Brady's remarks to the Senate inquiry suggest the incident resulted from inadequate communication between teams responsible for system updates and operational maintenance. The company has not detailed specific remedial measures announced during the hearing.
