The CEO of Optus, Kelly Bayer Rosmarin, steps down after a network failure.

Following the statewide outage over two weeks ago that disrupted phone and internet services for fourteen hours, Kelly Bayer Rosarian has resigned as Optus’ CEO.

Following her attendance at a Senate investigation into the outage on Friday, Bayer Rosmarinus said in a statement issued by Singtel, the parent company of Optus, that it was time for her to stand down.
Bayer Rosmarin stated, I had the chance to testify before the Senate on Friday to go into further detail about what caused the network outage and how Optus recovered and responded.

Additionally, I was able to convey Optus’s resolve to uphold customer service standards and win back their trust. Now that I have had some time for introspection, I have concluded that it is in Optus’ best interests to proceed with my resignation.

Optus said on Friday that the outage was caused by a configuration problem with over 90 Cisco routers, which were unable to handle modifications to the routing information received from Singtel Internet Exchange (STiX) following a standard software upgrade.
The business has stated that modifications have been taken to ensure that the same problem doesn’t arise again.

Prior to taking over as CEO in April 2020, Bayer Rosmarinus, 47, served as deputy CEO for a year at Optus. Yuen Kuan Moon, the group CEO of Singtel, praised Bayer Rosmarinus influence on the company, citing increased staff engagement, greater financial performance, and increases in market share.

Kelly was hired by Optus at the start of the epidemic, and we are grateful for her leadership, devotion, and hard work at this difficult time. We also acknowledge Kelly’s leadership and service to Optus.

But when a corporation was the target of a cyberattack in 2022, Bayer Rosarian managed the largest data leak in Australia’s history, which was followed by this year’s outage.
