Welcome to the Community!
I've managed to locate your account using your Community details and did initial checks on the line. There appears to be no line fault that could be service affecting, as we speak.
Nonetheless, we are glad to see that the internet is back up and running for almost a day now.
Should you still require further assistance, you may reach out to us again or you may check out our self-help options located here: http://tpg.com.au/support
