More than 200 of Optus’s customers were unable to call triple zero during the 14-hour outage, the company’s chief executive, Kelly Bayer Rosmarin, revealed to a Senate inquiry on Friday.
Bayer Rosmarin and the company’s head of networks, Lambo Kanagaratnam, faced a two-hour grilling before a Senate committee on Friday, chaired by the Greens communications spokesperson, Sarah Hanson-Young. Questions explored the outage itself as well as the company’s communication to customers and what will be done to prevent it happening again.
