I know of cdn.debian.net which knows how to do ASN lookups since the
last weekend. Mirrorbrain which runs behind the mirrorlist for opensuse
and openoffice.org also uses ASNs as well as Fedora's MirrorManager
which I have already set up for RPM Fusion. IF there is interest I can
help set up a MirrorManager instance.
MirrorBrain is on my ToDo List, maybe we can get together and look at
pro/cons for those systems. Peter from mirrorbrain should also be
reading here (are you?). I am off for a week though from friday on, but
this is something where I wanted to wait for 6 to be published and
tackle it after that.

Can you send the complete content of that page, so that I can see which

I attatched two files.
One is the content of http://isoredirect.centos.org/centos/5/isos/x86_64/.
Another is the content of
http://isoredirect.centos.org/centos/5/isos/i386/ for

comparison.
Yeah, the i386 is correct, for x86_64 I see correct numbers for the
actual isos (8 hosts each), for the DVD I see 3 hosts and for the
directory I also only see three hosts, which isn't correct indeed.
The number of DVD hosts isn't correct either for x86_64 (and i386).
Thanks for notification, I'm not sure yet what that is.

Hi,
well, Fedora has been having the Mirror-Manager for quite some while now
where you can select which countries your mirror would want to serve and
also give your networks (lately: your AS-numbers) and would always be
ranked first in the mirror-lists.
I've tried to discuss that with CentOS-folks in the past, but they
seemed to prefer the current system which "just works" for them :-(
Sorry to hear that, while we're wasting bandwidth :-(
Kind regards,
 Stefan Neufeind

There are other mirroring systems which can also act on a BGP or simple

If there are systems capable of using BGP then why is everyone using

You are not helpless here, and it may well not be the right 
solution (from a CentOS risk management) to risk breaking 
update settings for a huge deployed base in a major release
No-one is preventing you from running a local mirror, and 
dropping in local yum configs to point to them
No-one is preventing you from having a cacheing proxy server
There are so many hours in the day -- there is no constraint 
that you wait for Ralph or anyone else, before you block out 
an implementation and propose it for testing.  If you have 
data needs in doing the setup, please ask here.

Hello All
If the CentOS Master Mirror want to announce and meeting, the date
can't be fixed by getting input from member of list.
We, the maintainer of CentOS mirror around is a part of CentOS family
and we are human being. Everyone has their own work schedule. Like in
6th October, Internet Society [ISOC] has conference in Bangladesh for
first time and I wish to join the event. 12th October is my birthday
etc etc.
So it would be better fix a date and announce it via list. If most
people don't agree to join on said date, the date of event can change
1 to 3 days plus and minus.
...
From my point of view, it seems if the GeoIP database of CentOS is up
to date, currently problem might solve in most case. Among other
distribution, CentOS mirror maintaining system is the most easy system
in current scenario.
If we want to move from current system, then ASN based system to
determine closest mirror might work.Though It also have pro & cons. So
my suggestion is to work with current system  and find out where is
the problem so that the problem can be fixed.
Best Wishes
Ahamed Bauani

I am not sure about that. Getting to know the timeframe which people
have and if they are interested at all helps a lot when determining a
date for such an event.

So it is neither the 11th, nor the 12th nor the 13th :)

I guess weekend is out of the question anyway?

I then propose Monday, October 18th(!) at 20:00 UTC,

See above.

It is up to date (well, from now on it will, at least). One problem is
that the data sometimes really is off, so machines in the UK are
flagged as being in the US or Canada and things like that.

Second: It doesn't help in cases when you'd like all the machines in
your DC to hit the mirror which also is in that DC. If you aren't the
admin of all of those machines, using the same AS or /16 would be
great. And that is what our mirroring system cannot do.

Not really :)

The problem is that we can *only* do GeoIP. The granularity of that
isn't fine enough at times (see above or other examples in this
thread).

Monday 18th at 20:00 UTC? I know that that again is a week later, but
I don't really have time to prepare something for the 12th, looking at
my schedule.

I do want to do some homework before a meeting like that but am away
for the complete next week.

I just made an offer for a meeting via IRC.

Monday, October 18th, 20:00 UTC.

And keep in mind please that that means to move a *large* installed
set of machines over to a different mirror system. And that system is
run by a crowd which doesn't really like changes in their eco system.

So the more people can chime in with their knowledge ...

One thing I know is that we won't begin restructuring *before* 6 is
out. Just to give an unknown timeframe >:)

Cheers,

Ralph

I would be interested in joining the discussion, and that day/time so far
works for me.  To make it a little easier to schedule, here is a link to
that day/time with local time calculations around the world:
