Telstra CEO points to undocumented software change for outage in Senate testimony

Telstra CEO Vicki Brady told a Senate inquiry on Friday that last week’s outage at Australia’s largest telecoms firm was likely caused by an undocumented design change and a missed software update on a network time-keeping device.

Last Wednesday’s outage, the latest in a series of incidents to hit Australia’s telecommunications ‌sector over ⁠the past ⁠few years, cut phone services for thousands of customers, disrupted wireless payments and halted trains.
