Welcome back. If there is not enough players of the map you want to play in, you can now try nice robots locally to replace them:
Levels and Robots (Simplified Version). My server DiverSion is online regularly with those settings (a nice CTF map similar to Ducati and a nice FFA map similar to Easy Tank's Superserver (good to say that both maps are something like the default randomly generated BZFlag maps)), though it's not 24 hours. (Note the server has an important modification to allow 'autopilot' robots online since, otherwise, they are forbidden.)
I play it regularly and it's rather fun and challenging. Some people which bear the lag, since it's South America, also like it (though it's not so much lag).
I take the opportunity to emphasize that, to play comfortably, Mini Ducati maps maximum of players is 3 vs 3 and normal Ducati is 5 vs 5. More info, on my thread.
