20260526 / HPC power down

There will be a total power down today (Tuesday 26th of May 2026) of the HPC power lines in the datacenter to (hopefully) track down the root causes of last week events… Expect a whole day power down, starting 9h00.

EDIT 11h45: testing done.

And in the middle of this, there's a security upgrade…

GW will restart, all (remaining) login nodes will restart also.

Don't work on PSMN today.
