Perhaps you assumed (or like I, was told by Support) that throttling is sure to prevent your bandwidth going over limit, but as the KB says:
Note, throttling is only updated once a day! So even with throttling on, it’s still possible for you to go over your limit if you suddenly get a large abnormal spike in traffic in one day.
