The severe outage that shut down ANZ's payments system for several hours yesterday afternoon will have disrupted numerous payrolls scheduled to reach employee bank accounts overnight.ANZ described the systems strife as a "technical fault" and said it "affected internet banking, the goMoney app and the ANZ app late yesterday morning."The bank also listed "ATM, eftpos or mobile payment apps such as Apple Pay" as affected, but in different ways.In a curious twist, ANZ said "customers currently cannot make transactions of more than $200" across ATM, eftpos and Apple Pay.While the bank believed it had resolved the issue by around 4pm yesterday, roughly five hours after it started, the angst on social media continued into last night. The bank's social media team repeatedly posted that "our systems are slowly coming back online."Outages of this nature are less common than they once were, making the ANZ incident a talking point among payments systems experts.The Payments System Board in its annual report commented on "significant operational retail payment systems incidents as well as ... less severe disruptions to retail payment systems," without sharing the data it collects from banks.'There were fewer significant incidents in 2016/17 compared with 2015/16," the PSB said, while "the total duration of significant incidents also fell."
