Nick -- Oh most definitely. One thought I had previously was an opt-in where users who update with yum can opt to have transfer rates sent back to centos.org. But that's treading into deep waters... When I say "test the server" I mean in a distributed sense. I.e. multiple servers are checking from many geographically diverse regions. Any one faulty checking server can easily be identified in a sea of working ones. That idea pushes up the bandwidth usage for checking, however. But even if checking uses a gigabyte of bandwidth per month, that's nothing compared to the overall bandwidth they will see in the same time period. Some acceptable ground should be there somewhere. --Graham On Tue, Aug 24, 2010 at 4:20 PM, Nick Olsen <Nick at 141networks.com> wrote: > Only problem I see with this is it would be dependent on what the mirror > could pull from the other mirrors. > Lets say the "checking" server is in the US, and the server being > checked is in Australia.
