Ubuntu 9.10 (Karmic Koala) just came out today.  I think their server is 
overloaded but you might have local mirrors.  For example:

http://ubuntu-releases.cs.umn.edu/

I'll wait a few days to update my Ubuntu machines.

Looks like the kernel.org mirror is still responding pretty quickly if all 
you need is an iso. I'd imagine the apt repositories are another story 
altogether!

I used a torrent to download.  Almost done now.  Speed is between 40KB and 
400 KB or so for me.
