Whether the game panel is up, on both of the machines it needs.
About this page
Pterodactyl comes in two halves. The panel, the site you sign in to, runs here on the VPS. Wings, the service that actually holds the game servers, stays on the media server because that is where the servers are.
Both have to be up for the console to work, and only one of them is on this machine.
Signed-in sessions
gcp.ameribrit.netSigns everyone out of the game panel at once. Passwords, two-factor and API keys are left alone, and the game servers keep running.
About signing everyone out
Everyone signed in is returned to the sign-in page. Nothing else about an account changes: this is about who is signed in to the control panel, not about the servers it controls.
The panel reports how many sessions it removed, which is not the same as how many people were signed in: the game panel starts a session for every visitor and encrypts them, so they can be counted but not told apart.
