Welcome to the Community!
Using your community details as reference, I was able to pull up your account and I can see that you were in contact with our Technical Team earlier. From what I can tell, this issue has been escalated to our Engineering Team due to a line fault that NBNCo needs to address. An NBN technician appointment has been booked already. Further updates regarding the case and the outcome of the tech visit will be provided to you directly via SMS or phone call by one of our Engineers. If you have other concerns, feel free to leave a comment on the thread.
