Hey,

I'm still interested in hearing about how the mirrors perform for
different people.

I've now setup a test mirror in Singapore, in addition to the one in the
US. Plus, there's bishan, which is hosted in Germany.

So, here are the 4 domains which serve bordeaux.guix.gnu.org nars by
geographical location:

  France:     bordeaux.guix.gnu.org
  Germany:    bishan.guix.gnu.org
  US:         bordeaux-us-east-mirror.cbaines.net
  Singapore:  bordeaux-singapore-mirror.cbaines.net

Chris
