Commonwealth bank of australia outage -
But why, of all times, the CBA rolled an upgrade on a Thursday — usually a no-go period for fixes because of the high number of payroll runs — is a very live and open question. So far the bank is only offering words of contrition for the outage, but a number of factors already in the public domain surrounding its tech stack offer some pointers.
In terms of infrastructure, CBA is known to be a heavyweight Dell user across its platforms. As reported by iTnews, Oracle shipped a very large critical patch update earlier this week , some of which carried vulnerability scores as high as 9.
Sleep deprived staff at the CBA declined to talk to the infrastructure or security issues, saying instead that the bank took responsibility for the outage and was working to resolve problems and issues for customers hit by the mammoth glitch. We are working through the backlog as quickly as possible, but rest assured that all payments both into and out of customer accounts will be properly processed.
An urgent incident autopsy is also underway as the CBA moves to ensure the problems do not repeat. Notably, eftpos and ATM services were not hit by the outage and continued to function. However customers of banks using batched transactions, which are the most common way to move chunky drops like payroll or scheduled bill payments, could have to wait until Monday or Tuesday before funds flicked across by the CBA clear because many do not process over weekends.
Most so-called neobanks are already real-time because they are greenfields builds that have never been near a mainframe. They will also likely snare other refugees from the Big Four. The biggest headache in terms of payment delays will be payroll, which again raises questions as to why CBA rolled an upgrade on a Thursday. On Thursday night contractors working for the NSW government received emergency messages from labour hire and recruitment agencies warning them that while payrolls had been lodged, it was not clear when they would clear.
Banks are required to formally report outages — many of which occur without media coverage — to the Reserve Bank of Australia, which has started keeping a log of incidents to guard against a lack of resilience becoming a systemic risk. All rights reserved.
