[CentOS-mirror] CentOS-6 CDs decision needs some stats

[Bill Glick]

Yes, these stats were only for our HTTP traffic on mirror.ncsa.illinois.edu.  Our stats included a ton of 206, 400, 404, & 503 errors that skewed our numbers.  Here are our revised stats that ignore those error codes.

Month    5-CD 5-DVD 4-CD 4-DVD
Jun 2011  234   206  269    67
May 2011  646   477  590   156
Apr 2011  632   451  556   249 
Mar 2011  472   436  689   834
Feb 2011  335   261  377   102
