[mirror-admin] Gigabit NIC saturated.. [Re: Fedora 9 bitflip... slow becauseof the updates

[Voll, Toivo]

We (ftp.usf.edu) got slammed at between 400 and 500 Mbps for the first
twelve hours, and it's been dropping steadily since to the current pace
of about 150 Mbps. A factor is that our poor box is way underpowered and
deals well with people that want to suck down isos through a fast
connection, but dies when the hordes with download accelerators and slow
connections arrive. About half of the initial traffic was over Internet
2.

Which leads me to two questions: 
1) The apache rewrite rule on the wiki page to prevent ranged http
requests produces a syntax error in my CentOS Apache install
(specifically the actual rule, the rest of the config is fine), any
ideas why it might fail or how to combat the download accelerators? (I
am already running connection limiting, but network installs get a bunch
of simultaneous requests going too, so I can't limit it too far.)

2) Since we fell to Tier 2 status, I was wondering what the mechanism /
policy is for us to get rsync access to the release prior to the bit
flip? Do Tier 1s provide a different rsync view depending on the
mirrormanager ACL or by request, or how is this handled? Do they
restrict the availability of releases at all and I was just trying
mirrors that weren't synced yet? My apologies if this was already
discussed somewhere and I missed it.

Thanks for sending this.  I'm curious how our other mirrors saw the
traffic load yesterday/today as well.  From Fedora Infrastructure
team's perpsective, the release went very smoothly - which I largely
credit to our great mirrors!

Glad to hear it!
