Optus' chief executive, Kelly Bayer Rosmarin, has said "technical network issues" were behind the outage and there was no indication of a cyber attack. The outage impacted all internet, cellular and fixed-line services using the Optus network across Australia. Optus, Australia's second-largest telco and owned by Singapore-based SingTel (Singapore Telecommunications), has contacted its customers to offer them "at least 200GB of extra data" to thank them for their patience during the outage. In September 2022, Optus suffered a data breach which resulted in the leaking of information about their customers, including their names, birthdates, addresses, contacts and passport or driving licence numbers.
