Dear de.NBI Cloud Bielefeld Users,
the University Bielefeld is scheduling a diesel generator/power outage test on the whole building complex. These tests also afflict our cloud infrastructure. In order to protect our hardware from any unexpected power losses or power spikes, we will shut down all compute nodes during the generator tests.
28th September 2020
10:00 – 18:00 CEST
This means, that all running instances will power-off in result. To prevent any filesystem damages or corruptions on your instances, please shut them down gracefully in advance.
We recommend to shut down instances a few hours (or one day) before the planned schedule as we will start to shut down compute nodes @ 09:00 CEST.
After the tests are done, you will be able to restart your instances again and continue your work as usual.
We will remind you about this event one week and a few days before the downtime.
