[Systems] [Sugar-devel] Broken ASLO mirrors

Our CDN works like this:

1. mirmon checks periodically if mirrors are responding and up to date

2. clients send queries to download.sugarlabs.org (sunjammer)

3. mod_mirrorbrain in apache uses geoip to find the closest *WORKING* mirror

4. apache sends back a 302 redirect to the chosen mirror

5. user downloads the file from the mirror


So, no matter how many mirrors are broken, you should *never* get
redirected to an error page. Can anyone show me a "wget --save-headers"
showing the problem?
