Telstra Mobile Network Failure

Faults reported to DownDetector, on 8 July 2026.

Telstra's mobile phone network failed just before 4 am today. The Australian Science Media Centre (AusSMC) asked for expert comment, so I wrote a couple of paragraphs about it: 

"Telstra's mobile network problems appear to have started just before 4 am today, based on faults reported to DownDetector. The problem peaked just after 6:30 am, with a steady improvement since then.

Apart from consumers' phones, the network is used for transport & mobile payment systems.

It is too early to say what the cause was, but from past experience I expect it was due to a software upgrade which went wrong, not an attack.

One way you can protect yourself at home from such outages is to have phones on different networks.

A widespread long-duration outage, particularly of the Testra network, could be very inconvenient. But it is not going to be catastrophic."

Just as a household can cushion the effects of the loss of one network by having phones on different networks, financial and transport companies can have a backup network programmed into their systems. This will cost a little more, but allow service to continue when one network goes down, for whatever reason."
