Internet connectivity interruption
Adelaide and Perth were returned to direct-service connectivity at 6:24pm AEST last night (Monday 18 May), completing the restoration of all city POPs to their normal upstream paths. The network is now stable and operating in its normal configuration across all locations. Our work now shifts from active restoration to investigation and remediation. We are continuing to work with our upstream providers to understand the full picture of Friday's event and to identify structural changes that will reduce our exposure to a similar attack pattern in future. A portion of the technical investigation is being handled in cooperation with the Australian Signals Directorate under an open case. A full post-incident review will be published once the investigation phase is complete and the ASD engagement is at a point where we can share the technical picture without compromising it. We will notify status-page subscribers when that is available, on a timeframe of weeks rather than days. To reiterate from earlier updates: this was a network-level denial-of-service event affecting the reachability of our public IP space. It was not a security breach or intrusion, no customer systems were accessed, and no customer data was involved in any way. Customer workloads continued to operate normally throughout. We will leave this incident open in a monitoring state until the post-incident review is published. Thank you for your patience throughout, and for the constructive feedback received from customers over the weekend.
