For the record, you should always let it run pings for at least a minute. Also keep in mind pinging is going to be a little less accurate because it is a game server not a webserver, so it's not supposed to have new visitors on such an extreme level.
Far as the actual server goes, I can't really say. It might be something on your end or something on sourceop's end. I don't run it so I can't really comment.
