Article mentions a cyberattack on the Pensacola base after the shooting. I don't remember seeing that reported anywhere else:
"A state of emergency declared by New Orleans Mayor LaToya Cantrell remained in effect for the city of New Orleans after a cyberattack Friday prompted officials to preemptively shut down computers and servers connected to the city.
The incident is being investigated by city officials, Louisiana State Police, the Louisiana National Guard, the FBI and the Secret Service.
It is not clear when the systems will be back online or who was behind the attack. The New Orleans cyberattack came days after a cyberattack downed computers in Pensacola, Florida, after an attack at its naval base."
