I wouldn’t assume that is the case. The failure modes are different that is all.
I saw a whole corp POS platform a couple of decades ago that was hanging off a TFTP server on a machine that no one dared turn off in case the world ended. One day the DC UPS failed, it didn’t come back up and they had no retail operations for several hours while they sent a bunch of cash to a guy who had left to help them fix it.
There’s stuff like that everywhere lurking in the archaic.
I know of a modem in a DC which is used to talk to a branch office running AS400 hardware that is so old they have to buy spares off eBay.
