Will it > completely replace our check-mirrors script? I've got a crawler that runs every 6 hours comparing against the filelist available from the master rsync server at the time the run starts. It's pretty fast, multi-process, using keepalive HTTP HEAD and FTP DIR calls to determine presence and size of files - close enough for our purposes. So yes, it replaces check-mirrors. It doesn't (yet) replace mirrorlist.cgi - the app that returns the mirror lists to the yum client. It generates files usable by mirrorlist.cgi as-is. Or almost does. That piece needs some work... :-) I've started looking at the GeoIP library too. Turns out, you can get the continent from the country 2-letter ISO code, so we could return mirrors on the same continent. MirrorManager has a list "Countries Allowed" on a per-Host basis, so for instance the mirror in Belgium could dictate it can only accept clients in Belgium. (yes, that's actually a restriction that mirror has, but it's just described in the html for the entry, not enforced by Fedora code anywhere yet). As for more mirrors, we've added several in the last few months with good connectivity in countries we haven't had previously: China, Mexico, better bandwidth in Canada, ... but most mirrors are still having trouble syncing. I don't want to add a bunch of new mirrors until we get some of the other infrastructure pieces, namely storage and storage bandwidth, straightened out.
