Quite possibly, yes. There's also the consideration that such an outage would likely be part of an even bigger problem. Over here, like most of Europe, we're pretty safe from natural disasters aside from storms causing local power outages. There are no earthquakes, tsunamis or similarly destructive events. So a hypothetical situation where payments are down nationwide for a significant period of time would almost certainly be part of an even larger disaster where a lot of infrastructure is non-functional due to military attack or something akin to a complete crash of all computers.
