Hi there, on Friday (March 6) the head node and the big storage for ci.guix.gnu.org will need to be moved to a different aisle in the MDC data centre. This will require a short downtime as we need to shut off ci.guix.gnu.org for a little while. We will also take some time to apply firmware updates, which will delay the reboot.
We expect that this will take less than a day. -- Ricardo
