Last week, we discovered that a bunch of military bases – especially Air Force bases – were blocking TroopTube, the Pentagon's YouTube knock-off. Today, we learned that the digital blockades were part of a larger, Air Force-wide decision to cut off access to the military's taxpayer-funded, security-scrubbed, low-bandwidth-optimized video sharing site.

"The Air Force must balance network security requirements with competing requests for wide-ranging access to a vast array of public internet services for our Airmen. Air Force-wide policy restricts access to categories of sites that are generally not mission related, and put adverse performance demands on our networks. As a result of this general policy, access to Troop Tube is blocked at Air Force bases," service spokesman Major David Small e-mails Danger Room.
