The FBI released the statement below concerning the NICS outage on April 2, 2006
On Sunday, April 2, 2006, the FBI Criminal Justice Information Services (CJIS) Division's National Instant Criminal Background Check System (NICS) experienced a loss of service as a result of problems encountered during scheduled maintenance on the Interstate Identification Index (III) Segment of the Integrated Automated Fingerprint Identification System (IAFIS). The maintenance consisted of significant changes to support a future migration to a storage area network. The III outage was planned for 10 hours beginning at 12:01 a.m. on April 2, 2006, with the NICS planned to startup at 10:00 a.m., a two-hour delay in service. However, even though the system change procedures had been tested, the technical staff encountered several issues that prevented the restoration of III services within this planned window. As a result, the NICS did not return to service until 11:45 p.m. on April 2, 2006, a near 16-hour interruption in NICS Services. The FBI undertakes every effort to minimize service outages to our customers. We apologize for any inconvenience this outage has created.
