I fully agree on the snark, but if anyone seriously considers backup from grid...

Get an islanding-capable inverter separating your internal power setup from grid, connect it with battery systems - you can control battery charging and have "microgrid UPS" then. Combine it with solar power feeding as second feed into inverter. Scale battery and solar panels as needed. If you have third input, can add three-phase genset (I recommend looking for propane fueled one if you don't want to care about fuel going bad)

That's what a UPS and a backup generator were for, even before PV and industrial-scale batteries became a thing.

Large consumers often have two independent grid feeds.

Do you disambiguate between failure of the grid and failure of the usine? Like failure of the power generator is not the same as cut wires. And in terms of AI and internet providers - both can be easily diversified.

Besides, what is it that you guys expect from a large scale provider of essentially experimental technology being tuned live as it goes? Is amazing this all works so good considering the complexity underneath.
