Most likely, this is the result of a flaky name server somewhere along
the way. I've noticed a similar effect with our Sun servers: if they
lose the connection to the world for a while, they start claiming that
hosts are nonexistent

It can actually be quite hard to navigate if the connection to
Wisconsin gets cut off: some sites are aliased to franz, whose web
server then redirects requests. This goes for cran.dk.r-project.org
for instance. Also, the link from the R home page to CRAN is to
cran.r-project.org which requires a nameserver lookup. (Of course if
you *know* that the DK site is really http://sunsite.dk/R, and that
the sources in Austria are at http://www.ci.tuwien.ac.at/R/src,...)
