The numbers here are impressive. But I find myself wondering about those smaller, 15-second attacks they later mentioned in the article; were those actual _attacks_, or is it more likely, given their smaller scale, short duration and (relatively obscure?) targets, is it more likely those were TESTS in preparation for something bigger?<p>I suspect the latter but I admit I’m not an expert in this area, so more educated views are wholeheartedly welcome!
