Can I still see a server's IP address and details when it's down?

Yes. For every linked server FrontierStack remembers what it last saw while the server answered: OS, hardware, uptime, IPv4 and all addresses, stable IPv6 addresses (link-local and privacy addresses left out), the Tailscale IP and MagicDNS name, public name, DNS resolvers, connection type, the services running then, any reboot the operating system was scheduled to make, and the monitor's settings. When the server stops answering, its pane shows these dimmed with a clock icon under an orange Not answering line, instead of blank fields, and the AI Administrator can read them too. The record is kept only on your Mac, in an owner-only file, never includes tokens or alert URLs, and is forgotten when you remove the server.
