If you're having trouble connecting to the TeamSpeak server at "sdw.ts.nfoservers.com" after the latest TeamSpeak client update, you can use the non-hostname IP 104.153.105.2:28340 and you will be able to connect just fine. The hostname (sdw.ts.nfoservers.com) and above IP go to the exact same server.

The main IP will be fixed soon.

TL;DR: Use IP 104.153.105.2:28340 if you're having issues connecting after latest TS update. Nothing's changed.
