Pentagon limits some access to MySpace, YouTube, other Web sites

WASHINGTON — Lt. Daniel Zimmerman, an infantry platoon leader in Iraq, updates his blog on the Internet every now and then "to basically keep my friends and family up to date" back home.

It just got tougher for him — and a lot of other U.S. soldiers — to do that. No more using the military's computer system to socialize and trade videos on MySpace, YouTube and more than a dozen other Web sites, the Pentagon says.

Citing security concerns and technological limits, the Pentagon has cut off access to those sites for personnel using the Defense Department's computer network. The change limits use of the popular outlets for service members on the front lines, who regularly post videos and journals.

"I put my blog on there and my family reads it," said Zimmerman, 29, a platoon leader with B Company, 1st Battalion, 28th Infantry Regiment.

"I keep it as vague as possible," he said. "I'm pretty responsible about it. It's just basically to tell a little bit about my life over here."

He's regularly at a base where he doesn't have Defense Department access to the Internet, but he has used it when he goes to bigger bases. He'll have to rely on a private account all the time now.

Memos about the change went out in February, and it took effect last week. It does not affect the Internet cafes that soldiers in Iraq use that are not connected to the Defense Department's network. The cafe sites are run by a private vendor.

The ban also does not affect other sites, such as Yahoo, and does not prevent soldiers from sending messages and photos to their families by e-mail.

Internet use has become a troublesome issue for the military as it struggles to balance security concerns with privacy rights. As blogs and video-sharing become more common, the military has voiced increasing concern about service members revealing details about military operations or other information about equipment or procedures that will aid the enemy.

At the same time, service members have used the Web sites to chronicle their time in battle, posting videos and writing journals that provide a powerful, personal glimpse into their days at war.

"These actions were taken to enhance and increase network security and protect the use of the bandwidth," said Col. Gary Keck, a Pentagon spokesman.

The Pentagon said use of the video sites in particular was putting a strain on the network, and also opening it to potential viruses or penetration by so-called "phishing" attacks in which scam artists try to steal sensitive data by mimicking legitimate Web sites.

After the warnings of the shutdown went out, military members were allowed to seek waivers if the sites were necessary for their jobs. Often insurgent groups post videos, including ones of attacks or — in some high-profile cases — of U.S. or coalition soldiers who have been captured or killed.

If the restrictions are intended to prevent soldiers from giving or receiving bad news, they could also prevent them from providing positive reports from the field, said Noah Shachtman, who runs a national-security blog for Wired Magazine.

"This is as much an information war as it is bombs and bullets," he said. "And they are muzzling their best voices."

Among the sites covered by the ban are the video-sharing sites YouTube, Metacafe, IFilm, StupidVideos and FileCabi; social networking sites MySpace, BlackPlanet and Hi5; music sites Pandora, MTV, 1.fm and live365, and the photo-sharing site Photobucket.
