thianb:
short answer: no
long one: you should really consider the fact we can't help you if you don't help us to understand your problems..
what does "it keeps on trying to download a primary file from all of the available mirrors and fails to download the file" mean? we are (very) far from you, your server, your monitor and can't see/read..
if you have problems to access repositories:
- you have network issues (do you have a firewall/UTM appliance in fronto of your SME?)
- you have SME issues, so it's time to report it in bugzilla (link is above)
