Planned Guix services downtime on May 10th

[Maxim Cournoyer]

Hello!

The Max Delbrück Center [0], which graciously hosts the Berlin Guix
infrastructure, will be conducting upgrades to their data center.  The
Berlin fleet of machines will have to be powered down between 01:00 and
06:00 (Berlin time) on May 10th, which will cause the following service
disruptions:

1. https://ci.guix.gnu.org downtime (use bordeaux.guix.gnu.org instead)
2. https://issues.guix.gnu.org downtime (use Debbugs instead [1])

The website should remain available, if the fallback in place works as
expected.
