Have you had a chance to check our Network Status page for any faults or outages that may be impacting your service?
I would also recommend running through the steps listed on our NBN & Cable Home Internet troubleshooting support page to check if this would restore your connection.
I have also included the link to our Troubleshooting mobile internet connectivity support page in case you were referring to an issue with your mobile data.
Should the issue persists, we recommend messaging us via the My Optus app for further assistance.
