Failing over is correct because there's no way to discern that the hardware is not at fault. They should have designed a better response to the second failure to avoid the knock-on effects.

I don't think anything in this incident pointed to a hardware fault

The software raised an exception because a "// TODO: this should never happen" case happened

A hardware fault would look like machines not talking to each other or corrupted data file unreadable

Upon inspection it was evidently not a hardware failure. The computer didn't know that at the time, and hardware failure can look like anything, so it was correct to exercise its only option.
