[SAC] CDN for osgeo4w

[Matthias Kuhn]

Hi,

I have recently been using osgeo4w here and there and noticed that 
download speed is not that fast (around 500 KB/s here). I have been 
advised that using the listed mirrors is faster and that's indeed the 
case, which is very good. However, I think this does not completely 
solve the issue. 1. it is unclear if all repositories listed there do 
serve the same content or have company specific additions / purpose and 
2. even if this is the case and communicated transparently, there is no 
clear strategy on picking the best mirror.

So I was wondering if it would be possible to use a CDN for this purpose 
or if there are particular reasons not to implement such a system. As 
far as I know qgis.org is provided through cloudflare, not sure about 
other osgeo resources.

I have seen that keycdn [1] offers free services for open source 
projects, but maybe there are other services already in place.

I am keen to hear opinions on this topic. I think for the average end 
user it would be a huge benefit to only have to focus on the choice 
*what to download* and having some smart technology take care of the 
*where from*.

If the idea is generally well received, I'd be happy to write a mail to 
KeyCDN or help if possible.

Best regards

Matthias
