First the Public Server is hosted by 4Players. In the past, the officially Official Public Community Server was 1 Server. You also saw the developers of TeamSpeak and you could also ask them questions about TeamSpeak. After a while the TeamSpeak Public Community Server was divided into 2 servers, no idea why. After the division, there was still support from the TeamSpeak employees on the Official TeamSpeak Test Server, but this was also discontinued after some time. Today the TeamSpeak Employees are very rare online. I am a TeamSpeak Admin on the TeamSpeak Public Community Server (no employee or server admin)
If you have question, feel free to ask.
I hope the Official Public Community Server will have more users in the Future. : D
The Server Nickname is: Official TeamSpeak Public Community Server
