Fwd: [PATCH] treewide: use CDN for downloads

[Ted Hess]

Yes, cache coherency could be an issue here. I think the problem is 
inherent with a CDN and co-dependent objects. Or... am I just imagining 
this?

Let's proceed as jow says and then go from there. I'm not 100% convinced 
that a CDN is what we need for downloads as objects are constantly 
changing.
