The debian distribution on master looks very different from the distribution on ftp.cdrom.com. I notice that the alpha stuff has moved from sid to slink. This is a good thing. What is odd is that the slink/main/binary-alpha on master is complete while ftp.debian.org is missing much. The version of sid on ftp.cdrom.com no longer has all of the packages so we're left with a very incomplete archive. I checked the au mirror and see the same thing.
