Hello,

Right now, ci.guix.info points to berlin.guixsd.org, the front-end of
the build farm hosted at the MDC.

The previous setup was that mirror.hydra.gnu.org mirrors hydra.gnu.org
(the actual build farm front-end) using an nginx proxy:

  https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/nginx/m=
irror.conf

This provides a bit of redundancy that we don=E2=80=99t have currently for
berlin.

Thus, I=E2=80=99m thinking about using a similar setup, but hosting the mir=
ror
on some Big Corp CDN or similar.  Chris Marusich came up with a setup
along these lines a while back:

  https://lists.gnu.org/archive/html/guix-devel/2016-03/msg00312.html

Compared to Chris=E2=80=99s setup, given that =E2=80=98guix publish=E2=80=
=99 now provides
=E2=80=98Cache-Control=E2=80=99 headers (that was not the case back then, s=
ee
<https://lists.gnu.org/archive/html/guix-devel/2016-03/msg00360.html>),
caching in the proxy should Just Work.

I would like us to set up such a mirror for berlin and then have
ci.guix.info point to that.  The project should be able to pay the
hosting fees.

Thoughts?

Would someone like to get started?  You=E2=80=99ll undoubtedly get all the
appreciation of each one of us and a beverage of your choice next time
we meet!  :-)

Thanks,
Ludo=E2=80=99.
