To keep such outages in mind, banks usually assign the maintenance windows on weekends and preferably during low traffic times, i.e. post mid-night.
Such outages may very well reflect on the venues that are connected to the bank, in which case you would see a card transaction refusal. It is the job primarily of the merchant to be well-informed of such maintenance windows as scheduled by the bank.
