When the Physical World Votes: Grid Events and Disasters
Faraday's read: the industry spends fortunes on redundant software and then bolts it all to a single grid interconnection, a single fuel supply, and a floodplain nobody re-checked after the last hundred-year storm arrived early. The uncomfortable pattern in the big physical outages is not exotic. It is a backup that was never truly tested under load, or a correlated failure that took out the primary and the spare together. Diesel that will not start. A cold snap that freezes the very gas plants meant to carry the grid. Physics does not read your service-level agreement. It sends a bill, and it always cashes the check.

Why can having two independent utility feeds still leave a data center exposed to a single regional event?
Show the answer
Because independence on paper is not independence in fact — two feeds can share the same regional grid, fuel system, or weather exposure, so a wide-area event like an extreme cold snap or a cascading grid failure can knock out both at once, defeating the redundancy.
