Hi. I recently upgraded my R installation to 2.11.0 on Windows XP (SP3) without changing any firewall settings. When I attempted to update my package list, the 'Select a mirror' took much longer than it normally did, and after I finally selected the site, I saw: --- Please select a CRAN mirror for use in this session --- Warning message: In open.connection(con, "r") : unable to connect to 'cran.r-project.org' on port 80. The only action I performed in a prior session was to download and install several packages including Bioconductor. Any idea what the problem might be? Thanks, Caitlin [[alternative HTML version deleted]]

[R] Unable to connect to 'cran.r-project.org' on port 80.
There was a notice earlier today about a power outage affecting the main
CRAN site..
For installing packages, try:
install.packages("packagename",
repos="http://cran.wustl.edu")
or to perform an upgrade:
update.packages(repos="http://cran.wustl.edu")
until the main CRAN site has been resolved. You can also google for
alternate CRAN sites to use in the repos= area as well. Bioconductor I
believe is on it's own site, not affected by the outage.
