Mastercard revealed that a widespread payment outage in Australia, which caused thousands of transactions to be declined, was due to an internal systems fault.

◆ ◆ The Wire takeaway

Your payment system reliability just moved up the agenda as Mastercard's outage shows single points of failure can still disrupt thousands. If you run fintech infrastructure, patching and redundancy should be your immediate priority this week.
