Commonwealth Bank of Australia (CBA) has been forced to take to Twitter and Facebook again to apologise to customers unable to access online accounts or use ATMs and point-of-sale terminals.
The bank has used its Twitter account to apologise for the latest outages to have hit Netbank customers and cash machine and eftpos users over the last few hours.
Says a tweet: "The issues are related to network connectivity problems. We're working to restore services as soon as possible. Sorry for the inconvenience".
CBA has also posted an update on its Facebook page which has been flooded by angry customers complaining that they have been unable to access services and that their accounts are not showing correct balances.
Many users have told the bank of their intention to switch accounts although some have tried to inject a little humour into proceedings, with one Facebook commentator, Peter Throne, arguing: "if commonwealth bank did this more often I might be able to fix my crippling alcoholism".
The latest glitch comes almost a year to the day since an outage left CBA customers unable to access their account information and less than six months since bank's ATMs, eftpos and call centres were all knocked out.
Update
Services were up and running by around 11pm local time following an outage that lasted up to five hours.
