Hi @Terley888,
Welcome to Community!
Telstra is currently experiencing a service disruption, which is affecting multiple services. They have booked a technician to check your TPG service anytime between now and 10/Mar/2020. Though it shows that your internet is working, there is still a possibility of service interruption until Telstra fully resolves the connection issue.
We apologise for the inconvenience.
Regards,
