It is not true. You forget user need to run apt-get `update' and
`upgrade (or install or so)'
Site A and Site B is CDN member, user query for cdn.debian.net
will be returned both Site A and B's IP (the query answer includes
two IN A entries)
When Site A's debian tree is newer than Site B's debian tree,
* It is OK, both apt-get update and upgrade (or install or so)
access to same IP, e.g apt-get update fetch from Site A and
apt-get upgrade fetch from Site A)
* It is not OK, when apt-get update and upgrade
access to deffernt IPs, e.g apt-get update fetch from Site A
and apt-get upgrade fetch from Site B. In this example stuation,
Site A's Packages file is newer than Site B, some packages
will not be able to download from Site B.
