(FOX News) - 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."
People at the Pentagon told FOX they were still able to use email on their computers, but were unable to access the internet.
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."
A spokesman at DISA told FOX so far "there is no indication of an attack" and it is expected the internet will slowly come back online.
Technicians in the military are working to resolve the problem, which could be affecting as many as 20,000 military and civilian personnel in the Pentagon alone.
