Maintenance: GWDG Cloud Server infrastructure

Message-Id: 201804091042
Time: 12.04.2018, 17:00 - 18:30 o'clock
Affected: GWDG Cloud Server
Impact: Loss of network connection of the virtual machines for few minutes

On Thursday, 2018/04/12 at 5:00 pm we will maintain the GWDG Cloud Server infrastructure. Although we expect that there will be no disruption, there is a risk that network connection of the virtual machines can be lost for few minutes.
Background: With this maintenance, the virtualized network components of the GWDG cloud server infrastructure are being moved to new, more powerful hardware. This usually happens without loss of network connectivity for the virtual machines, as long as everything goes according to plan.
