The Army admitted Thursday to not only restricting access to The Guardian news website at the Presidio of Monterey, as reported in Thursday's Herald, but Armywide.

Presidio employees said the site had been blocked since The Guardian broke several stories on data collection by the National Security Agency.

Gordon Van Vleet, an Arizona-based spokesman for the Army Network Enterprise Technology Command, or NETCOM, said in an email the Army is filtering "some access to press coverage and online content about the NSA leaks."

He wrote it is routine for the Department of Defense to take preventative "network hygiene" measures to mitigate unauthorized disclosures of classified information.

"We make every effort to balance the need to preserve information access with operational security," he wrote, "however there are strict policies and directives in place regarding protecting and handling classified information."

In a later phone call, Van Vleet said the filter of classified information on public websites was "Armywide" and did not originate at the Presidio.
