I forgot to change that, 2 weeks ago i got a e-mail from my host saying: Our new data-center is finished! <some specs> We will be moving the servers! ---------------
Sorry for that.

By the way, can someone add a function to the mirror-status so you can let it sort sites on other things then country?

Also i found out that i made a error in the cron settings, instead of
it syncing once every 12 houres, it synced every 12 DAYS, i fixed it, hopefully fixing the low ranking

Oh, by the way: What's "mirror age, daily stats" at the mirror list? I'm increasing the sync rate to once an hour.

I've got the bandwith and speed for it, I once pulled all 7 install iso's (at the same time) from a high
ranked mirror, it took me 16 min.
Then did the same but now used my mirror, it took me 15 min. My bandwith is enough. Ps. I know what a busy server is. I get a bonus from my host if i have a lot of traffic. I forgot the tier of the site and i removed the --delete flag. (my mail software is broken and the webmail i'm using can't handle
the e-mail format of the list-admin, so i can't read the mail in which he told me the tier).
I'm ready for it!

I'm curious as to what a busy mirror is...
We are currently delivering about 60GB a day of CentOS files...
does
that put us at the bottom or near the top? ;)

from 'busy' -i meant more like kernel.org / heanet.ie or
mirrorservice.org

Tiering the mirror distribution is pretty common, and honestly
makes
things a *LOT* easier for everyone. I agree with the sentiments
already
stated, automation is what makes this all doable. Removing things
like
--delete from your mirrors, is just a PITA. Yes accidental
upstream
removals will happen, but if the mirror infrastructure is
structured
well it will propagate out and the fix will propagate out quickly.
The way I've normally seen it is a small number (say 10) mirrors
are
allowed to pull form the master machines, and servers are then encouraged / forced to pull from those tier 1 mirrors. This means
the
tier 1's can pull more often from the upstream, and everyone else
can
make better use of the 1 & 10 gbps (and associated big hardware)
links
some of the bigger mirrors have. Personally I think it's
worthwhile,
and it's not too hard to implement.
Keep in mind that the 'busier' servers (kernel.org at least) are
in
a
better position (hardware / bandwidth) to support a greater number
of
people pulling from them. I would guess many of those "unused"
mirrors
may not be able to support the deluge you could potentially be
pointing
at them, this isn't universal but it's something to be aware of.
