The US military reduces the Information Operations Condition (Infocon) to Normal—the lowest possible threat level—less than 12 hours before the 9/11 attacks commence, reportedly due to reduced fears of attacks on computer networks.
Level Reduced Due to ‚Decreased Threat‘ – The Infocon level is lowered to Normal, meaning there is no special threat, at 9:09 p.m. this evening. The reason for this, according to historical records for the 1st Fighter Wing at Langley Air Force Base, Virginia, is “a decreased threat from hacker and virus attacks on the computer networks across the US.”

Since October 1999, the commander of the US Space Command has been in charge of Defense Department computer network defense, and has had the authority to declare Infocon levels. General Ralph Eberhart, the current commander of both the US Space Command and NORAD, is thus responsible for evaluating the threat to US military computers and issuing information conditions—“Infocons”—to the US military. He is presumably therefore responsible for lowering the Infocon level this evening.
