Commands smoothly transition to 2000

PETERSON AIR FORCE BASE, Colo. — As expected, the year 2000 rollover was not a significant event
for North American Aerospace Defense Command, United States Space Command, or Air Force
Space Command. Each command smoothly transitioned to the year 2000.

Command officials report seven minor computer-related “anomalies” in non-mission critical systems
occurred during the rollover period. In each case, contingency plans were successfully executed
resulting in no mission impact.

“To date, we observed seven minor Y2K anomalies out of approximately 440 mission systems,” said
Air Force Lt. Col. Gary Warren, Air Force Space Command’s Y2K project lead. Anomalies included
some space surveillance sites that correctly rolled the time and day but continued to display the
year 1999. The correct year was manually updated. There was no mission impact.

U.S. Space Command’s Computer Network Defense officials report they monitored only normal
activity throughout the rollover period. “The Defense Information Infrastructure is operating
properly, and we have no indications of any malicious activity during the Y2K transition in the form
of unauthorized intrusions,” said Col. Tom Muckenthaler, USSPACECOM’s Chief of CND operations.

“The commands’ preparations over the past four years included remediation, replacement, and
evaluation of all systems,” said Air Force Maj. Dan Mullen, NORAD/USSPACECOM’s Y2K program
lead. “None of the commands’ missions were impacted due to the rollover into the next millennium.”

“Our Y2K preparation efforts were highly successful,” said Maj. Gen. Harry Raduege, chief
information officer for the commands. “Though we were well prepared to respond to Y2K
anomalies, we were not surprised by the largely uneventful transition to the Year 2000. We will
maintain our vigilance through the leap year transition dates.”
