I'm not a pkgsrc guru, but I think for a particular build (or a bulk
build session) pkgsrc has to cache temporarily the list of sites that:
1) are down
2) do not contain the requested source files
otherwise when a package contains a list of many small source files,
pkgsrc will attemp to download each file from the same list of sites,
even when the first site is down or does not contain the files.
