Commo Blackout - I Never Knew

On, "Married to the Army - Alaska" there's been much talk about the 'Commo Blackout'.    During my husband's 1 year deployment in Afghanistan I never really noticed Communication Blackouts. 

 Here's why...

I talked to my husband on the phone once a week.  I spoke to him through email or messenger systems maybe every 3 days.  It's not like I could pick up the phone and call him and got a 'Commo Blackout' recording.  He communicated with me when he could.  Where he was at, there wasn't very good internet.  I was use to not hearing from him for days.  Commo Blackouts last, usually, no longer than 3 days.  It's more like 8-10 hours.
