Australians got a taste of a world without digital payments on Thursday afternoon when Telstra network outage took down ATM and Eftpos machines at some of Australia’s biggest retailers.

All services have now been restored and the telco has apologised for the impact and inconvenience to business and their customers.

According to the Telstra, the outage occurred from approximately 2.30pm to 5.30pm on 11 July impacting some of Telstra’s IP network services, including Eftpos, ATMs and some payment platforms.

Woolworths closed down self service checkouts and could only accept cash payments, which put shoppers in a tricky position if the nearby ATMs were also knocked out by the outage.

CommBank ATMs and CBA Eftpos terminals were impacted, as well as Bendigo and Adelaide Bank ATMs, ANZ Eftpos machines, Westpac ATMs and, NAB internet banking and payments.

Retailers impacted included Woolworths, BWS and Caltex. Dominique Lamb, CEO of the National Retailers Association told The Sydney Morning Herald the outage may have cost retailers up to $100 million.

Telstra said it is continuing to investigate the exact cause of this issues but early investigations suggest it was “caused by an unusually large volume of traffic across network links in NSW.”

“We apologise for the interruption to some data services yesterday afternoon. We know how frustrating this was and worked to restore them as quickly as possible,” a spokesperson for Telstra said.
