Another question regarding mirrors...

I've noticed that today when I execute an update command on my systems it is now resolving to my mirror for all but the update mirror. Based on the timehosts.txt file we can clearly see that my server has the quickest time, but for some reason the update mirror is never the same as the others:

Determining fastest mirrors * addons: mirror.science.uottawa.ca * base: mirror.science.uottawa.ca * extras: mirror.science.uottawa.ca * updates: centos.mirror.netelligent.ca

Is there something that dictates which mirrors are update mirrors?

I was wondering, how does the "fastest mirror" algorithm work?

Very simple/naive, compares ping response times, see /var/cache/yum/timedhosts.txt for last-used values (which I sometimes tweak by hand to get mirrors I want).
