Yes, there's been some problems with the Bioconductor server the last
few days, e.g. http://bioconductor.org/biocLite.R is not working
either. It was down on Monday night too and then it was not possible
to install any packages from them. I think they are aware of this
problem, but maybe not that it is down in this very minute. I've
cross-posted this reply to the bioc-devel to make sure the right
person gets it.
However, a HTTP 404 response should not crash R regardless. For
instance, the code for install.packages() tries to download
PACKAGES.gz and if missing it tries to download PACKAGES. All of a
sudden I started to receive reports for OSX users that tried to
install my packages from http://www.braju.com/R/ saying my code core
dumped their R session. I didn't have PACKAGE.gz and it worked for
everyone but OSX users. It sounds like they've located and solved
this problem in R-devel by the end of July.
