TPG relies on the NBN Co’s infrastructure to deliver our NBN services. These infrastructures are not fault free and on occasion, may be affected by unplanned outages which can subsequently affect the NBN service we deliver to you.
We recommend for our customers to check if their service is affected by a network outage. We've created an article that will guide you on How to Check for NBN Network Outage.
An online troubleshooting guide is also available here.
We understand that your service was restored yesterday as well and it's been running within specification.
If you need further assistance, please let us know.
