Scheduled downtime for the HPC2N region of SSC – 3/9 2018
One of the central network switches in the storage-infrastructure will be replaced due to a failed fan and to do this we must shut down all running instances in the HPC2N region on 3/9 2018 between 08:00 and 12:00.
This will only effect the HPC2N region and will not have any impact on instances running in the other SSC regions.
However login via the web dashboard to the other regions will not work during this maintenance period.
