After we changed IP of ours teamspeak 3 server the rank page disappeared https://www.gametracker.com/server_info/ts.nvis.pl:9987
I can't even manage server cause of "The server you requested is not in the GameTracker database."
Here's google cache version http://webcache.googleusercontent.com/search?q=cache:NNS5NP6PzPcJ:www.gametracker.com/server_info/178.217.185.91:9987/+&cd=3&hl=pl&ct=clnk&gl=pl (ts.nvis.pl:9987 cache is unavailable but this is the same serwer)
(in case it doesn't work screenshoot here: http://i.imgur.com/MLDfZr5.jpg )

Old ip: 178.217.185.91 / New ip: 185.62.189.215

When the original server is still online, DNS is only re-resolved once every day. If the new server is down when GT initially tries, it can cause an error. Once it comes back online it should correct itself, which it looks like it did.

Thanks!
