You can manually adjust the settings to select your servers. If not, SpyOFF automatically uses the best server, which should provide the fastest connection.
However, there may occur inconsistencies, so a manual server selection might be useful.
To do so, please check "select server yourself" in the client under "Settings".
Afterwards you only have to save the settings. The server list is then displayed in the client thus enabling you to manually dial into any server.
