Welcome to the Community!
I'm sorry about the connection issue you've been experiencing. I can understand how frustrating it is not being able to get a working service.
NBN Co advised of a network incident caused by a local power outage that is impacting HFC customers in the Oatley, NSW area. The power distributor has not advised of an ETR.
Network Engineers are monitoring the situation and once the power is restored, will test alarms and perform health checks on the network to confirm stability.
Updates will be provided as soon as it becomes available.
