Botched Mastercard update left Australian shoppers stranded — payments failed for hours
Over the weekend, many Australian shoppers found their Mastercard payments declined mid-purchase. The US-based company confirmed the issue on Saturday and stated that its network is now back to normal. While the disruption technically hit Mastercard's global network, it was felt most acutely by shoppers in Australia.
An undisclosed number of Australian customers were unable to pay with their cards during Saturday's shopping trips. As reported by ABC, Mastercard quickly identified the cause of the new outage: a scheduled system update that went wrong, triggering declined transactions for a period of several hours. The situation was resolved by the end of the day, Mastercard said, though the company hasn't shared specifics about what the update was actually meant to do.
During the outage, many shoppers found themselves unable to complete purchases with a Mastercard-issued credit card. ABC reports that some shoppers tried backup cards without luck, and were ultimately forced to leave their carts behind and head home for cash. By the time they returned, the outage had already cleared and payments were working normally again.
According to Downdetector data, the outage left a clear mark on Saturday's shopping activity. Reports of card issues climbed past 1,700 by 3 pm, then fell back to 173 a couple of hours later. Most complaints centered on fund transfers and mobile banking, though cash withdrawals and Apple Pay were affected, too.
The incident serves as a stark reminder of how fragile the digital economy can be. Payment processors like Mastercard handle billions of transactions daily, and even a short-lived outage can cause significant disruption for millions of users. Mastercard has not yet commented on whether it will take additional steps to prevent similar incidents in the future, but the company emphasized that its network is now fully operational. Shoppers affected by the outage are advised to check their transaction histories and contact their banks if any issues persist.
