Bandwidth troubles could threaten Pentagon's new social networking rules

The Defense Department announced its seminal change in Web policy last week, following a seven-month review of its social networking rules.

Until now, the Pentagon had in place key restrictions on service members' access to a number of popular Web services, in part because of concerns those tools could strain its meager broadband network or present critical security risks to U.S. interests.

But it seems both concerns persist, even despite the Pentagon's stated change in heart. Still, Floyd insisted on Monday that the Pentagon had anticipated many of those challenges and within the next 180 days would prepare a more nuanced set of social networking guidelines addressing possible difficulties.

"I think, though, people will find quickly, as I did, as I started using it, the benefits of using this as a communication tool," Floyd later added, noting a change in military culture was under way.
