'fraid so.  This is how I get to Joerg, who's only about 150 miles
down the road:

There's also a question of net load.  If you look at the figures
above, you'll notice that the time from me to ipgate2.win-ip.dfn.de
was under .5 second.  From there to sax.sax.de (all inside Germany, in
the DFN), things rapidly go to hell.  I'm told that this is a normal
state of affairs.
