The US military’s Defense Information Systems Agency (DISA) on Thursday shut down access to the internet and blackberry service while work was being done to fix an unspecified problem.
The shutdown, which came around 10:00am local time, means that no one in the Pentagon has internet access. Many military downrange, including combatant commands, do not have internet either.
DISA, according to its website, is a Defense Department agency that provides command and control support to national-level leaders and joint-war fighters “across the full spectrum of operations.”
The agency sent out a network-wide notification Thursday morning via email explaining that “users are experiencing problems browsing the internet due to a DISA-wide outage.” As a result, the memo said, “ALL Blackberry, email web-browsing, and VPN services are affected.”
