Code review comment for lp:~jpds/launchpad/fix_361650

Morning Jonathan,

Country mirrors are official mirrors whose FQDNs have been CNAME'ed to a $CC.[archive,releases].ubuntu.com domain. This is why we refer to them as official country mirrors.

Stuart,

We're limited to one country mirror because it's not possible to load balance between two different Ubuntu archives mirrors because of limitations with the apt-get software unless the two mirrors are in perfect sync.

Also I believe, the plan is to, hopefully, auto-generate our CNAME DNS records of country mirrors using the ones specified in LP's DB by admins (with this patch). And it's not possible to have multiple CNAME records to a FQDN.
