"Low ping" and "High ping" seem to be interchangeable. When I have a server that is currently running fine, it tells me "low ping" (but with a green network icon), and when I have a server that is currently on low ping, it tells me "high ping" (but with a red network icon and a yellow warning message about Im going to play a low ping server?)
The message says "You don't have a strong connection to the chosen server. Your experience may be impacted.". This does not mean it is "low ping", but actually the opposite.
"Ping" is a measure of how much time there is before sending a request to a server and receiving a reply. Lower is better (faster). So a low ping server is good.
The graphic may be a bit misleading, so if you want to suggest changing that, you can do so on the Feedback site linked below.
