Bug Description
First, sorry, I haven't the faintest clue on where to file this issues on the ubuntu.com servers, so here goes...
I have been seeing some erratic behavior from the ubuntu.com servers for some time now when I am downloading files from the domain (~1 month, maybe more). Firstly when I start the download it screams down at a whopping > 6MB/s, this goes for the first ~100MB and then drops slowly down to ~6 KB/s within a few minutes.
For a concrete example I am seeing this just now with: http://
I probably wouldn't have reported this if it wasn't because I mentioned it to some of the other guys at the office and they had also experienced the exact same symptoms for some time now, making me believe that I am probably not out on a limb.
Otherwise my network connection is rock solid and generally very fast

I downloaded the karmic cdimage today, and saw similar behavior ... would fluctuate between ~300 KiB/s and 380 B/s.
tracert cdimages.ubuntu.com from right now (sorry, didn't think to check when I downloaded):

This isn't really a bug in Ubuntu, rather, it is a known problem of the internet: servers have finite bandwidth. The best solution would be to use a local mirror.

No need to be condescending Luke, I have indeed heard of this here "internet" before ;-)
How did you deduct that it is a bandwidth issue, and not a local IO issue on the Canonical servers?

Apologies, that was not my intent.
Anyway, the best place to discuss infrastructure issues is via IRC at #canonical-
I am attaching the output of 'mtr cdimages. ubuntu. com' in case it matters...
