"It's unfortunate but these things happen from time to time."
According to various news reports, both NAB's online and telephone banking systems went out this morning and were not fixed until late this afternoon Sydney time. You can follow the timeline of events on the bank's Twitter page.
The bank could not - or would not - say what caused these latest problems, but that unlike NAB's November on-line meltdown, it did say that customer transactions were not affected.
NAB naturally apologized to its customers for the latest inconvenience.
"Unfortunately, for a large organisation these things happen from time to time."
I don't think CEO Clyne was expecting the time interval between technology problems to be so short. Another major outage, and the bank may find the phrase, "These things happen from time to time," becoming its unofficial mantra. It may already be to the other Australia banks that have to interact with NAB.
NAB online customers were likely already in an irritable mood when today's outage occurred. According to this report today in the Sydney Morning Herald , a "communications system" glitch yesterday caused several old SMS and email messages to be resent to its UBank online banking customers. The bank would not say how many of its customers were affected by the glitch, but it is likely to be at least a few million.
The bank also apologized for this problem as well.
