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.”
According to a Pentagon official familiar with network security, the outage was not in response to any kind of cyber-attack. The official said if it were an attack, “we’d all know it and DISA would have done what is called a blanket protocol, shutting down all sorts of access until they isolated the source of the attack.”
