[R] http://cran.us.r-project.org/ inaccessible

[Ross Boylan]

For the last couple of days when I go to http://cran.us.r-project.org/ I
see only the left-hand margin logo and table of contents.  If I click on
one of the links there, I get a timeout.  Other sites (e.g.,
http://cran.stat.ucla.edu/) work fine for me.

Lacking complete confidence this is a bug*, as well as any better notion
of where to report this, I'm reporting it here.

*I have had problems accessing one other site,
http://www.oasis-open.org/, that is generally accessible.  It has been
suggested the problem is that oasis does not cope with congestion
notifications (ECN) properly, so it's not clear whether this is my
problem or the sites.
