It looks like posting on the AWS forums may get some support on the matter. Since we have tried an internal and external apt source, it would seem to be a problem with the EC2 instance and posting on the forums would seem to be the way to go.

Would it be easy to deploy a test instance somewhere else, like http://www.bigv.io/ or http://www.rackspace.co.uk/cloud-hosting/cloud-products/cloud-servers/ or your local machine and run a set of builds to test to see if we have problems outside Amazon's cloud?
