HAARP was shut down in early May 2013, awaiting a change between contractors who operate the facility. According to HAARP program manager James Keeney, "Defense Advanced Research Projects Agency (DARPA) is expected on site as a client to finish up some research in fall 2013 and winter 2014." The temporary shutdown was described as being due to "a contractor regime change." The Alaska Native corporation Ahtna, Incorporated is reportedly in talks to take over the facility administration contract from Marsh Creek, LLC.
The closure was first reported by the Amateur Radio Relay League on Monday. An article there quoted Dr. James Keeney, who now helps manage the HAARP project at Kirtland Air Force Base, as saying “Currently the site is abandoned. It comes down to money. We don’t have any.”
The shutdown is reported to be only a temporary one. Air Force officials are hopeful that the facility would open and resume operations the coming months. DARPA currently has a sizeable funding bloc allocated for additional ionospheric research in the fall of 2013, so it will likely have to be open for that research. So the notion that it is completely closed down is not quite correct, though it is certainly not operational at the moment.
The real facility is located in Poker Flats, North of Fairbanks, Alaska.
