After having terrible problems with Teamspeak on Sunday 21st, where for several hours we experienced a robotic like bandwidth issue. Plus the system going down twice. GMD heard back from the providers, who sent the following message:
We apologize for the difficulty you were having. Unfortunately, another client hosted on the same machine was the target of a large bandwidth denial of service attack. This issue has since been mitigated and service levels have returned to normal.
To combat this issue we will be looking into a backup Teamspeak provider. GMD would like to apologize to all the players for the inconvenience caused by this technical issue.
