A California man pleaded guilty Friday to charges that he shut down the 
data center responsible for managing the state's electrical supply.

Lonnie Denison, 33, is now facing as much as five years in prison and a 
US$250,000 fine after admitting to breaking a glass cover and hitting 
the emergency "off" switch at the California Independent System Operator 
(Cal-ISO) data center in Folsom, California, on April 15. By doing so, 
he shut off the power in the data center. He was formerly a contract 
Unix system administrator at the center.

Cal-ISO is the nonprofit organization that manages California's power. 
By knocking these systems offline, Denison effectively cut the state off 
from the energy market, leaving California vulnerable to blackout 
conditions. No blackouts occurred, however, because the data center went 
down at 11:23 p.m. on a Sunday -- a time when electricity demand is 
typically at a lull. "If this deliberate shut-off had occurred in the 
morning ... things would have been far more severe," wrote Matthew 
Amant, the California Highway Patrol officer assigned to investigate the 
incident, in an affidavit.

It's not clear why Denison would have wanted to flip the switch on 
California's power, but according to U.S. attorneys, he was in a dispute 
with co-workers and just minutes before the incident had discovered that 
his computer privileges had been revoked.

Prosecutors allege that he followed up the power outage by sending an 
e-mail bomb threat the next day to an unnamed Cal-ISO employee, saying, 
"Hey, at one point I respected you ... you have a new kid. So this is 
only because of him. Get out before the timer expires. Not long now. 
Take care."

Following this threat, Cal-ISO evacuated about 500 employees from all 
three of its Folsom campus buildings, transferring control of the grid 
to a second control center.

That same day Denison spoke with a friend, admitting that he had tried 
to "shut off the power grid," according to a statement from the U.S. 
Department of Justice.

The Sunday night incident knocked the data center down for about two 
hours, but it took 20 computer technicians about seven hours to fully 
restore the system. The total cost of the outage is estimated at 

Denison, of Sacramento, California, is set to be sentenced on Feb. 29, 
2008, in federal court.
