Darkeagle let me know about some lag issues you were having with the TF2 match server, so DCH kindly moved it to a different server for us. The new IPs are:

Server: 81.19.217.198:27018
SourceTV: 81.19.217.198:27050

The server itself is unchanged, it has just been moved. Please pass the new details around and let me know if the performance has improved.
