Make Juniper Downloads Go Fast
Juniper software downloads come from a Really Weird CDN. It's not very good. It caches, and the fill from the upstream servers is really slow. Here in New Zealand, if the software image is not in the cache - if it's new, or if it's not super popular - it goes at about 10mbit/s.
I've set up a proxy server in Oregon to help with this. It only accepts connections for cdn.juniper.net and only HTTPS.
Example:
curl --proxy juniper.networks.fail:3128 -o <filename> https://cdn.juniper.net/blah
Get the URL from the download page - the one that says "To download the image directly on your device, use the following URL:". Copy that, that's the https://cdn.juniper.net bit.
The filename can be whatever you want, but you probably want it to match the Juniper one. Remove the < and > symbols.
Cheers.

ps. I did this while bored waiting for software to download.
