But a spokesman for the Army Network Enterprise Technology Command (NETCOM) told the Herald that the restrictions were routine to "mitigate unauthorized disclosures of classified information."
"We make every effort to balance the need to preserve information access with operational security, however, there are strict policies and directives in place regarding protecting and handling classified information," Gordon Van Vleet wrote in an email published by the newspaper. "Until declassified by appropriate officials, classified information — including material released through an unauthorized disclosure — must be treated accordingly by DoD personnel."
There is no word as to any Army restrictions on the websites of American publications — such as The Washington Post — that also published reports based on the leaked documents provided by former NSA contractor Edward Snowden.
Update at 1:26 p.m. ET. Not Blocking Websites:
A Defense Department spokesman tells us that the DoD is "not blocking any websites."
Instead, it is blocking offending content.
"Should any website choose to post information the department deems classified, that particular content on the website will be filtered and remain inaccessible from DoD networks so long as it remains classified," Lt. Col. Damien Pickart said in an email.
