Maintenance: GWDG Cloud Server Service – Migration networks to new networkcontrollers

Message-Id: 202201281126
Time: maintenance window Thursday, Feb. 03, 2022, 5:00 p.m. - 7:00 p.m.
Affected: Users of the GWDG Cloud Server service
Impact: None

During the maintenance window on Thursday, February 03, 2022, the networks of the Openstack projects will be moved to the new network controllers from 5:00 pm to 7:00 pm. For VMs with floating/public IPs we do not expect any disruption as the components for this are distributed across the compute nodes and are not affected. For VMs that only have private IPs, the network may be disrupted for a few seconds to minutes.
