I have looked into the case reference number you provided and it appears there is an unplanned outage affecting the Internet connection in your area. The fault is currently under investigation and we are working to resolve the issues as soon as possible.
To check on the status of the outage, you can visit our Network Status Page, click on Fixed Outages tab and enter your full address. You'll then see the outage reported and you can Report a Fault to enter your mobile phone number and be updated with the latest progress.
Please feel free to reach out to us by a private message via our Social Media pages (official Optus Facebook page or Twitter page) where we'll be able to obtain your details securely and look at waiving your plan charges for the down-time you've experienced as well as some options to keep you connected to the Internet.
Alternatively, you can reach us on a smart device via our Messaging service on the My Optus app 24/7.
