Planned downtime in the HPC2N region on Monday the 20th of April between 6-12 and Tuesday the 21th of April between 11-17, due to urgent electrical work. All running instances will be suspended before the outage and restarted again afterwards.
The other regions will not be affected by this and so if you can, we suggest move your workloads to the new WEST-1 region that is running a much more resent version of OpenStack on new hardware.
