Dear de.NBI Cloud Users Tübingen,
next Wednesday, May 14th, we will start important maintenance work including an update of our Openstack infrastructure. We will start on Wednesday and use Friday exclusively for testing and monitoring purposes, without change targets. The following week (from 19.05.) we will also continue with the maintenance work.
It is expected that for short time intervals of a few minutes no new virtual machines can be created or modified. Apart from this, there should theoretically be no disruption. As very extensive work is planned, we recommend that you take snapshots of your most important VMs until next Wednesday and pause any long-lasting operations until then or save any temporary results.
If you experience any disruptions at this time, please let us know. We thank you for your help and wish you a wonderful sunny weekend!
On behalf of the de.NBI Cloud Tübingen Team,
Fabian Paz
