Based on their report, we have identified that the issue is with the network controlled by the Telstra. They've now arranged for a Telstra technician anytime between now and 14 September to check and sort this issue.

We will also be keeping a close eye on your case and will provide you with updates where possible.
I can see from the reports that a Telstra technician has been dispatched yesterday and has changed a faulty main pair.
We've also ran remote tests and can see that the internet should now be working.
