|What would it take to set up something like this? I can ask AARNET to
mirror the download.sugarlabs.org, if that's required.
+1. We ask AARNET to mirror download.sugarlabs.org via rsync. Then add
AARNET to the list of known mirror in mirrorbrain.
|Is the redirect automatic? That is, if someone in Australia tries to
download from sugarlabs.org, can they automatically served by AARNET?
|That would make our downloads much faster.
+1. The initial http request (very small) goes to the primary server hosted
in Boston by the Free Software Foundation. Using GEOIP to determine physical
locality and an Apache module named mod_asn to determine network locality
the download request is redirected to the best mirror. In the case of
Australia that would be AARNET.
