There is a new temporary address in the guild announcement with the updated TS3 name. Today, Microsoft claimed that some computers that were using the domain name no-ip was spreading malware. They disrupted service to thousands of legal users using no-ip. Microsoft goal is to find the malicious domain names and then reopen safe ones in time. We have no idea, when Microsoft will get to our domain name so please use the address in the guild announcement in the mean time.

No-ip has no idea when Microsoft would free their domain. So Tofu has created a new permanent domain for us. Check the info in the guild announcement for the new name :D. Thank you Tofu!
