There will be a two day maintenance on the cooling system and power feed 2019-10-16 - 17 that affects both Kebnekaise and Abisko.
The maintenance window starts at 2019-10-16 04:00 and ends 2019-10-17 18:00
The clusters will be down during that period and no jobs will be running.
During the days leading up to the maintenance only jobs with a short enough runtime to finish before the maintenance starts will be allowed to run.
So, if you have jobs that can use a shorter runtime it is advisable to submit them during the week(s) before the maintenance window.
