Lance,

Let's go at this from another angle.

How could this happen?

Here is my explanation:

1) As far as I am aware, the cAos site does NOT ask
distro users to download from public mirrors, rather
than from the master mirror.  

2) On install, yum.conf points to the master mirror.

3) Even if a distro user puts in a custom yum.conf
file that points to a public mirror, "yum update" can
remove the custom yum.conf file, and put in its place
a yum.conf that points to the master mirror.

4) From 2 & 3, I got the impression that it is OK,
even encouraged, to download directly from the master
mirror.  This is supported by the lack of any request
not to do so, 1.  

5) Maybe lots of other distro users got the same
impression as 4.  

That is my explanation.  

Does anyone have a better explanation for Lance's
analysis of the logs?

Rick
