Businesses are counting the cost of a mass outage which shutdown ATM and EFTPOS services yesterday.
The nation’s big four banks and major supermarkets were among those caught out in the failure, which began at around 3:00 pm yesterday and was largely resolved by 8:00 pm.
Telstra has apologised for the disruptions and says early investigations suggest it was caused by an unusually large volume of traffic across network links in New South Wales.
Russell Zimmerman from the Australian Retailers Association says retailers would have lost sales.
“In this day and age there’s a lot of retailers who probably don’t know how to use the manual click-clack system and even then, you have to be able to ring the bank if it goes over a certain figure to get authorisation, so there would have been retailers out of pocket, absolutely,” Mr Zimmerman says.
Meanwhile, Twitter users worldwide were unable to access the social-networking site for about an hour, with an outage that affected both mobile and web platforms.
Twitter said “an internal configuration change” was responsible for the outage.
On the web, users saw an error message that said, “Something is technically wrong. Thanks for noticing — we’re going to fix it up and have things back to normal soon.” An error message in the Twitter app said, “Tweets aren’t loading right now.”
According to website DownDetector.com, Twitter began experiencing issues around 2.46pm New York time on Thursday (0446 AEST Friday).
The highest concentration of user-reported technical problems were from Western Europe and the US. Australia was also affected.
Twitter service appeared to be restored about an hour later, at around 3.45pm local time (0545 AEST Friday).
