DNS hijacking?
It seems the secondary DNS for my domain isn't controlled by the same person any more, so if you're trying to get to my webpage(s), send me email, or ssh to my machine it might not be working sometimes (depending on whether it gets answered by the main server, or the secondary). I'm working on a workaround... sorry for any inconvenience in the mean time. (Seems it's a screw up at someone else's registrar :/ )
