Nov 20 (Reuters) - Australia's second-largest telco Optus' Chief Executive Officer Kelly Bayer Rosmarin has resigned, its parent Singapore Telecommunications (STEL.SI) said on Monday, days after a network-wide outage left nearly half the country without phone or internet for 12 hours.
Optus has appointed Chief Financial Officer Michael Venter as interim CEO.
Peter Kaliaropoulos was appointed to a newly created position of chief operating officer, SingTel added.
More than 10 million Australians were hit by the 12-hour network blackout at the nation's second-largest telco for much of Wednesday, triggering fury and frustration among customers and raising wider concerns about the telecommunications infrastructure.
