Running apt-get on EC2 without coughing up for a bunch of bandwidth charges

Question

I'm running Ubuntu on EC2 (using the alestic community AMI) and on startup my new instances use up a bunch of bandwidth running apt-get upgrade etc. Bandwidth between EC2 instances is free... anyone know if there's a mirror of the Ubuntu packages somewhere on EC2 I can use instead?

Answer 1

I'm not sure if there is an official one but Right Scale have offered up a repository for other users of ec2:

Answer 3

The Ubuntu Hardy, Intrepid, and (soon) Jaunty images published on Alestic.com already use Ubuntu archive mirrors internally on EC2.
