We're working through some issue with Black Ops servers at the moment. However, your server does appear to be hitting the max player count occasionally.

Is that graph consistently showing less players than are actually on your server?

Since the tracking was changed you can see on the graph that that it has not been reporting the correct number of players.

When the server has players in it, it generally stays pretty full. So when the graph is only reporting a few players it normally is wrong, it should be showing full.

Today was another example. Been full pretty much all day, and once again.. GT shows only a few players.

Thanks for looking into it.
