Hello folks, We plan to perform an upgrade of Software Factory deployments with version 3.7. The upgrade will be in 2 steps. On 2022-05-03 review.rdoproject.org will be updated and gerrit will be restarted during the upgrade. We expect that the interruption of services will be less than 3 hours. On 2022-05-04 we will perform the upgrade on softwarefactory-project.io (which hosts zuul and nodepool services). We expect that the interruption of services will be less than 4 hours. The affected services will be:     - review.rdoproject.org and softwarefactory-project.io gerrit services.     - Zuul CI not running jobs for gerrit, github or opendev.     - RDO Trunk not building new packages.     - DLRN API. Regards, Nicolas, on behalf of the Software Factory Operation Team
