In Holland on the first day of the month we set off all the war alarms for a minute to test if they still function. This month a lot of them failed, caused by the power frequency
Imagine for a second that North Korea or US were involved in the electricity dispute in question... And because of that, as you say, Holland wan't test it's war alarm (which is vital infrastructure I guess) I wonder what would be the position of EU...
Where this procedure is in effect, there's a different signal for "test" and "emergency". The opposite situation is more common - we've had a couple of cases where the person in charge actually initiated the emergency protocol instead of the expected test protocol.
