Optus boss Kelly Baer-Rosmarin apologized for the outage, which affected millions of Australian customers as well as major organisations.
“We are truly apologetic and sorry for our outage today, and teams are working extremely hard to try and restore services as a priority. We will continue to work on that until everyone is back at work,” she told ABC Radio Sydney.
The CEO contacted the program via WhatsApp and said she had no information about the cause of the network downtime.
“The team has tried a number of parts of the restoration, and so far, we have not gotten the results we were hoping for,” Bayer-Rosmarin said.
She added that some customers were able to access the Internet using WiFi, and said that the company would be able to provide updates on this aspect in the next hour.
But it also confirmed that Optus landlines were not able to call three zeros, but mobile phones were still able to contact emergency services.
The Optus boss added that “there is no indication that there is any connection to the Internet at this stage.”
