@nyrath @SecureOwl There are layers of protection against the influence of (solar) radiation. Some are physical (shielding), some are hardware (e.g. ECC RAM), some are software, for instance, maximizing the Hamming distance between the possible values of a variable or implementing some additional self-correcting redundancy for critical data. This could be a reason that a single make and model would be affected, as not all models share the same software (or in this case software version).
