RTT estimation will triangulate the minimum path delay and I hazard other info like flight exclusions and truck gps manifests will identify the locations. Nothing about datacenter locations stays secret long. (Obviously there are ways RTT can be fooled, misled or be inaccurate)

The location is not top secret. It is certified to host top secret data and applications (there are numerous regulations... so many that you'll want to self terminate...)

You may well be right. This from the ABC story linked above. They often misunderstand..

In short:Three data centres will be built in secret locations to host Australia's military secrets.
