Welcome to the Community!
I'm sorry to hear about the trouble with your connection. Your service was affected by an outage which was resolved at 1:17AM AEDST today. From what I can tell, your modem already reconnected by 1:11 AEDST. Do let me know if you're still having issues going online so we can look into it further.
As discussed in the thread you created, your connection should also be back by now.
