FAS Website Blocked by US Cyber Command, Then Unblocked

For at least the past six months, and perhaps longer, the Federation of American Scientists website has been blocked by U.S. Cyber Command. This week it was unblocked.

The “block” imposed by Cyber Command meant that employees throughout the Department of Defense who attempted to access the FAS website on their government computers were unable to do so. Instead, they were presented with a notice stating: “You have attempted to access a blocked website. Access to this website has been blocked for operational reasons by the DOD Enterprise-Level Protection System.”

The basis for the Cyber Command block is unclear, and official documentation of the decision that we requested has not yet been provided. In all likelihood, it is due to the presence on the FAS website of a small number of currently classified documents that were obtained in the public domain.

The basis for the removal of the block is likewise unclear, though we know that a number of DoD employees complained about the move and advised US Cyber Command that direct access to the FAS website was needed for them to perform their job.

The record of a 2015 hearing of the House Armed Services Committee on Implementing the Department of Defense Cyber Strategy was published last month.
