Yes, there is an issue with the BioC website (investigating) and I didn't mean to imply otherwise. For now, as you discovered, use http://www.bioconductor.org (note the 'www').

I only responded here because of the segfault you reported which most certainly is not a simple server-side issue :-)

Did you see the segfault with a recent R or an older one? If more recent, then it might be worth trying to reproduce and tracking down the bug.
