CentOS has developed our own mirrorlist and isolist applications and
inside this application, we have some countries that we shift to other
countries and we also have some country groups defined.
The purpose of these groupings is to have adjacent countries grouped
together for applications like fastest mirror and others.
I will put here what we currently have and ask the community to vet the
list for us to make it better.
Our major (large) groups are:
us - North
eu - Europe
ap - Asia Pacific
oc - Oceania
af - Africa
sa - South America
c1 - (Use High Bandwidth, don't know location)
Here is our current countries "with mirrors" to large group list (1st
variable is CC, 2nd is Group Code):
ar => 'sa',
at => 'eu',
au => 'oc',
ba => 'eu',
be => 'eu',
bg => 'eu',
br => 'sa',
c1 => 'c1',
c2 => 'eu',

====================================================We have created some smaller

This is our list of adjacent countries, so if you are in PH, you will
first get mirrors in conutry (PH), then from the small group (VN, CN, TW
), THEN from the large group (AP), THEN back filled from C1.
Or if you are in ZA, you would get mirrors from the country (ZA), then
from small group (IL, BR, TR, ES, IN), then from large group (AF), THEN
backfill from C1.
====================================================We also have a cross
reference having one country masquerade as another
for grouping purposes (countries with mirrors are on the right) ... here
is that list:

This is basically a cross reference, the countries on the right is where
we have mirrors, the ones on the left are the countries as returned from
an IP address.
======================================================
If anything looks bad, especially for people who are in the countries
and can tell us which ones are logically near (via the network) and not
necessarily physically near, please reply to this thread and lets see if
we can make the mirror network better.
Thanks,
Johnny Hughes

I am in Cali, Colombia, South America. Our route to Brazil, for one of many examples, would be via Miami/Ft. Lauderdale, Florida, USA. So, for us, in Colombia, it is much better to have a Mirror site in South Florida or the S.E. USA, if possible; since I do not believe there is one in Colombia. The fact that Colombia is adjacent to Panama, Brazil, Venezuela, etc., would make a Mirror in one of those countries faster, *if* we had a direct route on the Internet to them, but, we don't. I suspect for most countries in Latin America, this would be the same, since Latin America is so strongly connected to Miami, "the capital" of Latin America. Lanny

I could see a change for the fastest mirrors. For "extras" it chose mirrors.ucr.ac.cr About 1 1/2 hours in a nonstop jet from here. I'd never seen that before, so I'm sure it is a result of the changes you have been making. Lanny

[CentOS] CentOS Mirrors and Adjacent country groups

I downloaded that 4.3 MB file. I suspect we could peer with Panama. I believe like Colombia, they are also quite advanced with regard to telecommunications, and it's close. The city I live in (Cali) is actually much closer to Miami, Florida than Los Angeles, California is. And maybe we could peer with Peru, but that's a long way to our South. ---- Afaik it is impossible to deduce from the URL if one node is located nearby or far away. Eventhough as i live in europe, i can register and use a japanese URL. Secondly, i fond out that ISP do funny tricks with routing: My connection to my next-door-neighbour goes via a transcient node in New-York (high latency). Only traceroute can give you a clue if a node is local or not. And even then there is a question of available bandwith....
