Hello,
I was wondering, how does the "fastest mirror" algorithm work?
In my particular case, being a campus with large address pool I think it could be interesting if we could somehow force users from our subnet to use my mirror.

I'm in and out of here all the time, But I remember talk of a new-er mirroring system being in the works. With some functionality like fedora has where you can redirect your local subnets to your server, if its up to date. Anyone else remember this? Correct me if I'm wrong.
I know currently, You have to change the repo.conf file for each machine to point it locally.

I would love to see this happen for CentOS. MirrorManger works well for me with my local fedora mirror.

As said (maybe you weren't subscribed then): Work on that won't start before 6 is out of the door. But yes, I think the general thinking is that we want to get away from our generic system.

Which IP address do you get for mirrorlist.centos.org, when that happens?

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).

It at least does a connect() to the host in question.

Could/would be a nightmare in a large installation, but if you're deploying from templates or have a control management system in place I've had pretty good luck with inserting my local mirror as a baseurl before the mirrorlist.
baseurl=http://mirror.cisp.com/centos/$releasever/os/$basearch/ mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&rep...
I could easily be missing something obvious and dangerous here, but my testing seems to show it will read from my mirror first and if it fails for some reason move on to the mirror list. My main concern was accidentally breaking all updates if our mirror goes away for some reason, but it seems to handle it fine.
Obviously not as good as an updated mirror system, but something to maybe get some folks by.

Yes, that is exactly the purpose of having that line in the default config, although commented out initially.
But, it would still be nice to have the mirror list algorithm read in some IP addresses that would always put preferred mirrors in the top of the list.
We had some discussion on implementing Mirror Manager or some other more intelligent mirror management system. Has there been a consensus on which system to implement?
I personally like the Mirror Manager, and the way it handles a large mirror system like Fedora is really good!
