Apparently this Sunday is free data day,

As a small gesture to say sorry, we’re giving you — as a Telstra mobile
customer — free mobile data within Australia this Sunday.

Whether you’re on a personal or business, pre-paid or post-paid mobile, tablet or mobile broadband plan, you will automatically receive free data, from ​midnight ​to ​midnight in your local Australian time zone ​Sunday ​14 ​February ​2016.

A lot of it has to do with the massive increase in signalling as each user terminal tries to re-register with the HLR/HSS (3G/4G respectively).

That's why when you bring them back on you have to do it gradually... it is a highly reliable system generally and 4G is definitely more so than 3G.

Same thing occurred there, if and RNG failed, if the switch-over to the standby failed for some reason, the resulting registration storm caused the network to fall-over for 18 hours.
