The Air Force announced on Friday that it has lost thousands of records belonging to the service's inspector general due to a database crash.

"We estimate we've lost information for 100,000 cases dating back to 2004," Air Force spokeswoman Ann Stefanek told The Hill in an email.

"The database crashed and there is no data," Stefanek said. "At this time we don't have any evidence of malicious intent."

The database, called the Automated Case Tracking System (ACTS), holds all records related to IG complaints, investigations, appeals andFreedom of Information Act requests.

"The exception is senior official data which is maintained in a separate database," the Air Force said in a statement. "We also use ACTS to track congressional/constituent inquiries."

The Air Force said it was notified on June 6 by a contractor that administers the database of records that the data within was "corrupted," according to a statement.

The Air Force has launched an investigation to determine the cause of the crash, and is "aggressively" trying to recover the lost data and determine the severity of the loss, the statement said.
