how to save bandwidth while package upgrades

[Tapas Mishra]

Here is a mail in /var/mail/root which I received in my server logs
http://paste.ubuntu.com/532866/
I see same packages downloaded many times again and again.
The servers which are upgrading are total 5 (4 virtual machines and one host)
so is there a way I can save bandwidth on this sort of setup.
