I vote for higher, I have no fudge configured and my servers are claiming to be stratum 0 when I check them from outside. But!! Never trusting my observations until checking again, I see when I tested that my clocks were off. So if I cannot sync, my server continues to answer time queries but claims to be stratum 0. I am thinking I am getting closer to grasping this. DAve -- "Posterity, you will know how much it cost the present generation to preserve your freedom. I hope you will make good use of it.
