Australian operator Telstra has been hit with two more network outages in the span of three days, weeks after committing to invest to improve its network resilience.
On Friday, Telstra confirmed it was aware of an unplanned service disruption affecting NBN voice and data as well as ADSL customers.
Telstra said the issue its engineers have identified is “extremely complex, but in simple terms there was a fault with the device that manages the interaction between our network and all of the different types of customer modems.”
While the bulk of restoration efforts occurred two and a half hours after the company announced the incident, it took until late Sunday afternoon to resolve residual issues and fully restore services.
But on Sunday customers were reporting another outage affecting Telstra's mobile and broadband networks in Sydney, Melbourne,Brisbane and Perth, the Sydney Morning Herald reported.
Some customers reporting issues may still have been affected by the residual problems from the Friday outage, the report states. But the mobile outage, which affected data services for some customers, appears unrelated.
Telstra has been struggling with a spate of network outages over the past few months. The operator recently committed A$50 million ($36.2 million) towards addressing the issue by installing new monitoring equipment and improving its capacity to handle numerous simultaneous re-registrations.
