Changing Ubuntu Cloud Repo On Instance
Ubuntu instance images seem to utilize "nova.clouds.archive.ubuntu.com" as their default repository. It seems that either this server does not efficiently route to an alternate mirror, or it itself is a mirror. This results in quite abysmal download speeds that I have seen. Would there be any downside to picking any other Ubuntu mirror, that is definitively more geographically close to me, but not explicitly labeled a Nova/Cloud mirror? i.e. would there be issues encountered, or features lost, by not using Ubuntu's designated Nova/Cloud repo?

The setting of the repo location is likely to be baked into whatever image you grabbed. Running some DNS queries I suspect that *.clouds.archive.ubuntu.com is used to track requests from various cloud providers to provide insight into things like popularity of Ubuntu on different clouds. I wouldn't expect there to be any problems using a different mirror as the packages should all be kept roughly in sync. The biggest thing to keep in mind is probably reliability and adjusting if necessary.

not that im aware off. i think canonical are probly using this fqdn to track what installs are cloud based and what are native i highly droubt changing it would have a negitive effectr on your users expericne and using a geogravically colocated mirror would likely improve it. this is not to my knolage anything that nova or openstack ever had any discussions with teh ubuntu comunity about and it is not done at our request so i would just test it and deploy what works best for you and your users. if you have storage capasity and want to conserve external bandwith you might even consider hosting your own caching proxy/mirror to use as a default in the openstack cloud itself. that is quite common for ci enviornments.
