Optus Nationwide Outage Blamed on Routine Software Upgrade


Optus attributes last week’s nationwide outage affecting millions of Australians to a ‘routine software upgrade’ and announces steps to prevent future occurrences.

Optus Identifies Cause of Nationwide Outage

Optus has disclosed that a ‘routine software upgrade’ led to changes in routing information, resulting in a nationwide outage that impacted 10.2 million Australians and 400,000 businesses. The outage occurred last week and lasted for 14 hours, causing significant disruption.

Investigation and Network Restoration Efforts

The company stated that the outage was caused by changes in routing information from an international peering network, following the software upgrade. The impact was extensive, leading to the disconnection of routers from the Optus IP Core network. Restoration efforts required a large-scale deployment of technicians to physically reconnect or reboot affected systems.

Changes and Compensation

Optus has informed that changes have been implemented to prevent similar outages in the future. Additionally, the company has offered compensation to affected customers in the form of 200GB of extra data, aiming to address the inconvenience caused by the disruption.

Experts’ Views and Senate Inquiry

Experts have expressed concerns regarding the outage, attributing it to human error and pointing out the need for better disaster recovery plans and redundancy measures. As a consequence of the outage, Optus is set to face a Senate inquiry and various reviews as part of investigations into the incident.

Regulatory Response

In response to the outage, the federal government has announced plans to require telecommunication companies in Australia to report their cybersecurity measures, aiming to prevent similar incidents in the future.
