We need more Mirrors

mmcgrath-head
We've seen an absolute explosion in available mirrors lately, thanks almost entirely to the efforts of Matt Domsch our official mirror wrangler. Matt also put some maps together (below). It becomes clear that we need some more mirrors that are not in North America or Europe. We're doing ok in South America but could do better. In Africa and areas east of Europe we could use some help. India and China both have a solid concentration of users but China only has one mirror, India has none.




(Above) See a list of mirrors we have around the world.




(Above) This is taken from a sampling of Fedora installs that have recently contacted mirrors.fedoraproject.org for a mirror list. As most people know, our mirrors.fedoraproject.org site uses GeoIP to send people to a mirror that is geographically close to them. It defaults to global when none can be found (recent additions do have a few fall backs including continent before going to global). We love our mirrors and want to get some more.

If you live in an area that has few mirrors please take some time to try to find someone who can be a mirror for Fedora. Perhaps you already know someone who has a Fedora mirror and just hasn't registered it in Mirror Manager https://admin.fedoraproject.org/mirrormanager/ I'm particularly hoping ambassadors will take up this charge

Cool Graphics
Pictures do tell a thousand words.

I knew that the Fedora Project was global in scope, but this really brings it home.

How much room do I really need to run a mirror?
So how many computers are actually represented by those two dots in Alaska?
Is it worth it for me to run a mirror here at UAF? And how big of a disk would I need to mirror 7,8 and devel?

Re: How much room do I really need to run a mirror?
To mirror Fedora 7, Fedora 8 and devel you're probably looking at... 40 gigs? It doesn't have to be super fast or high end hardware. My mirror server runs on plain old IDE HDs, and a P3 800 mhz. It serves quite a bit of traffic too, no problems.

Is that 250g!?!

Re: How much room do I really need to run a mirror?
for a full mirror, yes, Fedora 7, rawhide, and the test releases, all architectures weighs in at about 250GB. If you're carrying the whole tree we're expecting mirrors to have about 1TB available. Mirrors are of course free to exclude whichever content they wish (e.g. not carry ppc, carry only Fedora 7 and newer, ...) and MirrorManager will figure that out.

Aside from disk space, we're looking for a minimum of a 100Mbit/sec network connection. Many of our mirrors offer a 1Gbit/sec network connection. In many cases, this really means our mirrors will belong to ISPs.

I understand that what we're asking isn't trivial.

we don't currently split up countries, so a US user will get one of the US mirrors, even if it's not the closest mirror to them. This spreads the load across all the country's mirrors.

Bad mirrors.
The problem with geographic serving mirrors is that it's not aways true that a near by mirror is faster then a far away one. Here in Brasil the academic network has a different infrastructure from the commercial one.

Well, I'm not sure if this problem All the mirrors are in universities and those usually have slower links and overcrowded networks. Well fact is that here in Brazil it usually faster and more reliable to use an American mirror.

Re: Bad mirrors.
Thats true, but for the majority of cases its a reasonable assumption to make. Especially since no other, simple, alternative exists without having the users pick and test mirrors on their own.

Re: Bad mirrors.
I agree, users should not pick their mirrors. If the overall quality of the mirrors served by fedora is good, then a user that do not know, or care, what a mirror is at the worst case get a slow mirror. The hard-core users that know and care about mirrors can fine tune themselves, with the fine possibly of shooting yourself in the foot.

I wish there were a logical map of the internet, something that would give you the nearest ip in terms of routing. The only problem is getting the information, maybe a collaborative effort using the yum-plugin-fastestmirror? The plugin would upload the relative ping times from all the mirrors he tried and a server would collect that and use the information to derive a graph that would have costs for each mirror relative to a host of different ips. :p gee talk about killing a fly with a cannon?

Accidents
Somehow time I climbed on is not present and, asking questions, found interesting and not so interesting answers. One of which was - « FailureAccident on the Chernobyl atomic power station, 4 power unit ». I became interesting and thumbing through sites was simply horrified. One I the fellow worker, in the past the meter man, has told about the friend which was the liquidator of consequences of this failureaccident, the truth or not I do not know. But spoke that - « firemen which extinguished a fire there, by turns washed in a showersoul groups, and muzhiks because of an irradiation were shone in darkness, but to live ithim remains few hours ».
