Another case where regulators should require a detailed public report
As per TSB and the BA failures. Where is the regulatory requirement that a detailed analysis and report be made available to all relevant bodies (all equipment and component suppliers, all their customers, all end users of the service and relevant regulators).
Contrast with a major aviation accident. The entire industry gets told the full details, is required to make recommended changes, and the details are available for scrutiny by any interested party.
Until the finance and it/networking industries are held to these standards, we will continue to suffer this sort of failure.
One positive mark to Visa though, for at least offering a superficial but reasonable explanation with little delay.
