Massive disruption caused by network issues impacts millions of Optus customers in Australia.

Telecommunications giant Optus has experienced a major outage, leaving millions of Australians without mobile and internet service. As the country's second-largest provider, Optus serves over 10 million individual customers and hundreds of thousands of businesses. The outage has had wide-ranging effects, including transport delays, disrupted hospital phone lines, and downed payment systems. While the cause of the outage remains unclear, Optus has stated that there is no evidence of a cyber-attack. However, the company had faced a significant data breach last year as a result of a cyber-attack. The outage, reported initially at 04:00 local time, has not yet been fully resolved, and Optus is working to restore services. The incident has resulted in people being unable to access emergency services and critical helpline numbers, as well as causing disruptions in train services. Other providers using the Optus network, such as Amaysim and Moose Mobile, are also affected. Meanwhile, Optus has faced criticism for a lack of communication with customers during the outage. Customers have expressed frustration over the inability to receive important updates, such as medical information or critical notifications. Australia's Communications Minister, Michelle Rowland, has called for transparency and timely updates from Optus. Optus CEO Kelly Bayer Rosmarin has apologized for the outage and assured customers that updates will be provided throughout the day.
