If you're in South Australia, chances are you're not reading this. Widespread blackouts across the state caused by severe storms mean that all of South Australia -- anywhere not with a backup generator or an uninterruptible power supply -- has gone dark.
The statewide power outage means that any mobile cell towers that are still operational will be running on battery backups or diesel generators. Many towers are already down across the state due to a lack of backup power or outages further up the backhaul network.
SA Power is telling citizens to get ready for extended outages, and to make sure they conserve mobile phone power wherever possible for emergencies.
Please brace for extended outages and ensure you conserve mobile device battery.
