Resolved -
We are currently monitoring an issue where merchants with Commonwealth Bank, Bendigo Bank and some merchants with NAB are unable to process transactions due to connectivity issues via the MasterCard network.
MasterCard have confirmed this is an issue in their systems and we are awaiting further updates. We will provide more details when available.
Merchants may be seeing an increase in transactions failing with the response code 91.
