Looks like some folks, including myself, have indeed gotten unnecessarily "excited" by this news. An update to the Ars Technica article on the subject (

UPDATE 11:40pm ET: Tammy Demel, a spokeswoman for Kennesaw State University, e-mailed Ars a statement.
"In March 2017, a Center for Election Systems’ server involved in an alleged data breach was turned over to the FBI. While the server was in the possession of the Bureau, a forensic image or copy of all the data on the server was made and held by the agency. Following the notification from the FBI that no data was compromised and the investigation was closed, the server was returned to the University’s Information Technology Services group and securely stored. In accordance with standard operating procedures, an after-action report was prepared. This report outlined hardware improvements for the Center, including repurposing the impacted server and surplusing servers that had exceeded end of life. As part of the report, the original server that had been investigated by the FBI was designated to be repurposed, and the drives on the server were erased and the server made available for alternative uses."
"As noted by the subpoena filed today by the Attorney General’s Office, the data and information that was on the server in question has been and is still in the possession of the FBI and will remain available to the parties in the event it is determined to be relevant in the pending litigation."
