As is usual, customers took to social media to vent their frustrations on the telco which last suffered an outage in the last week of June.
That outage was limited to services in Victoria and was due to a minor network fault.
Optus said Friday's outage did not affect data use, but only voice communications and was due to a hardware failure.

Used to be 24/7, & real ppl.
Now a recorded msg & then nothing.
"Please turn your phone off and on again. We appreciate your patience and apologise for the inconvenience."
#optus unable to make any calls from my phone. Any info on when you'll be back up?— Thunder (@H0RN3T77) 2 August 2018
