I used to work for two switch chip companies also. I know both of them has SW/logic in the switch chips guard against random errors in SRAM - "Alpha particles". I have seen detail test report that ran the system in nuclear lab and graph out the level of radiation level vs impact on the system error/recoverable error rate. I knew big customers (such as Cisco) can ask for such test reports and they do get it. It would be very interesting experiment to position some modem/old (7, 14, 28 nm chips) electronics (cell phones, raspberry Pi + solar panels) to various distant near nuclear accident site, monitor them remotely, classify and log the failure rate over the months/ years.
