The Teamspeak 3 Server is currently offline since 27..02.2020. Sorry for that.
I3D.net Support Feedback:
We have investigated this issue and came to the conclusion that the hardware is starting to fail. Given the current popularity of Teamspeak 3 servers in our Frankfurt location, we would like to immediately take this as an opportunity to consolidate our Teamspeak 3 services by removing Frankfurt from the list of available Teamspeak 3 locations. This would mean that on monday the 2nd of March, your Teamspeak 3 server will be moved to our Rotterdam location.
We moving the Server locations to Rotterdam. It will be soon available.
I'm sorry for the inconvenience.
If you have any Feedback or Problems you can pin me at Discord
