If a bank's systems are down consistently, use a different bank. Where public safety is not a concern, it is not any of your business as a private citizen what the inner workings of a private enterprise are, including the cause of outages even if they affected you directly.

That being said, of course I am much more likely to patronize businesses who do give me this type of information. Given a choice between a bank with satisfactory service and amazing transparency, and a bank with great service and no transparency, I will choose the former every time.

But government regulators opening up the working of private businesses is not a proportional response to your bill pay being unavailable for a few days.
