The report notes the missing data was discovered after an audit of 26 servers that was performed in August. The documents indicate the situation all boils down to insufficient management.

CBS 11 News has learned some of the data is not retrievable, while other parts are still available to the city and its business partners.

The loss of data happened when an employee was tasked with moving archived filed from online storage to a physical drive. The transfer was scheduled to take five days but was stopped halfway through — at that point some 22 terabytes had been deleted. The employee was fired on August 27, the same day the city revealed more data had been lost.
