The website of the Defense Information Systems Agency, the U.S. military’s main information technology arm, was back up and running Thursday afternoon after an outage that spanned five days. The public site had been out of service since Saturday–an outage that agency officials blamed on a hardware failure that also knocked out some internal services for DoD users.
DISA said the cause was a failure of a data storage system in one of its 13 global data centers, known as Defense Enterprise Computing Centers, or DECCs. The outage knocked out an estimated 10 percent of that particular DECC’s functionality.
Aside from the public website, the outage also affected the services that DISA provides to customers within the Defense Department. DoD personnel were unable to access some applications that deal with functions such as training, time and attendance and file sharing, but those applications were being incrementally restored, an agency spokeswoman said.
In addition to providing general information about the agency, DISA’s website serves as a repository for security training materials, security technical implementation guides (STIGs) and other information assurance products that are used by DoD and its partners.
