A hardware failure that's caused the Defense Information Systems Agency's public website to drop offline is now in its fifth day, DISA officials say.

In response to emailed questions, DISA officials say that a Nov. 12 Defense Enterprise Computing Center storage area network failure impacted 10 percent of the undisclosed facility's computing capacity, affecting DISA and other Defense Department agencies. DISA operates 14 DECCs, 11 of them in the continental United States.

"We restored many applications within the first 24 hours, making services available for customers.  We are restoring many applications each hour and making great progress," DISA spokeswomen Laura Williams said in a statement.

As of the late afternoon of Nov. 16, disa.mil continues to be mostly offline, although officials have restored the site to the extent that it now loads a notice of unavailability. Previously, a browser request to it would simply fail to resolve.

According to a June 9 presentation (.pdf) by a DISA field official, DECCs host many "critical, large-scale combat support applications."

UPDATE NOV 17: DISA tweeted at 1 p.m. that disa.mil is back online.
