Welcome to TPG Community!
For customers experiencing any issues with their ADSL service, we recommend the best thing to do first is check if there's an outage on the ADSL network.
Customers may visit our Service status page for outage updates
If there are no known outages in your area, customers can proceed with the troubleshooting steps indicated on this link : https://www.tpg.com.au/support/problems_connect_internet.php
In your case, there's a fault within the main copper pair that interrupted your service. Our Engineers lodged the fault with Telstra and the attending technician fixed the fault and restore your service.
Let us know if you need further assistance.
