I expect that we're seeing organizations dust off or setup new systems to warn their populations of incoming missiles as a result of the rising tensions with North Korea. There's an argument to be made that there could and are political motivations in addition to the concerns about safety. In any case, as these systems are powered up, updated, overhauled or even replaced, there's testing going on. And when there's testing, there's the opportunity for just this type of gaffe.
