Banking services were restored about five hours after the major outage struck on Saturday, leaving NAB customers across Australia furious.
A power issue was to blame for a series of faults that hit the bank’s mainframe in Melbourne, taking out its major services nationwide.
“It has had an incredible impact on our customers and for that we’re incredibly sorry,” NAB Business executive general manager Cindy Batchelor told reporters in Melbourne.
NAB says all customers are invited to speak with the bank about the losses they suffered in the outage and they will be compensated.
Frustrated customers shared their stories during the outage, including businesses that lost sales because they couldn’t process EFTPOS payments.
Customers overseas complained of being unable to pay for taxi fares and other things because of the outage.
NAB executive Anthony Healy took to social media to issue a video apology for the outage, saying it was “not good enough”.
