Neil: Thank you!  I didn't know trace route servers existed. From the
below, it looks to me as if there may be  a problem, at the router
past the last one I was able to get to, since the University of
Maryland and Careleton University trace route servers also got stuck,
just past where I got stuck. Possibly it's intermittent, since the
site is showing "up" and I was able to get to it, using an Anonymous
Web Browser. Snow in Houston?    :-)    Lanny
