It took out a bunch of Walmart systems. Only a couple hours ago was our east TN Walmart back in business since the bombing on Christmas. Cash only for over two days, and zero pharmacy business.
I'm saying that the notion of a water-cooled computer that relies on a nearby body of water, e.g. a river, for its cooling system, is preposterous. Nuclear power generator yes, computer system no.
Water cooled computer systems, back in the 70's when they were the state of the art, used a mixture of water and ethylene glycol, commonly known as antifreeze, and had a self-contained cooling unit. No need to pump in dirty water from a river or whatever.
Also a computer being permanently damaged by such an event is equally silly; forty years ago any mainframe computer system would have begun issuing "thermal checks" to the humans operating it and if nothing was done about it, i.e. human operators shutting the system down manually, it would power itself off before it "fried".
No offense, but this is a case of someone just making stuff up.
