At least here in Canada it is.
At ~1:30AM the phone rings. Now before I get jumped for answering the phone at that time, I have a 99 year young Mother and even tho she is in fairly good health one never knows. A female voice with what sounds like an authentic accent says `This is the`Australian National Broadband Network blah, blah, blah and in 24 hrs you will be disconnected. Please push #! to talk to a technician blah, blah, blah.
No I didn`t push #1.https://www.accc.gov.au/media-release/beware-of-nbn-scams
