If I were a betting man I would say its probably due to updates. In looking back when DS received his offer it was on Friday Feb 1, 2013. I would bet a cup of coffee the offers will be out no later than 1/30/2015 or sooner.
Site is back up and DS's status still says Boarded, so... still waiting ... patiently (if patiently means checking the site quite often!). DS was in the first board review and will join ROTC next year even without a scholarship as his goal since he was a freshman in HS is to be an officer in the Army. Just so excited for his future! But his future will happen with or without a scholarship right now.
