[aether-announce] Aether maintenance on Monday

[Marius Dan]

Dear Aether Users,

We will be performing cluster maintenance on

  **Monday, the 9th of September 2019 starting at 8 AM (Bremen local time)**

This will terminate all login sessions and all submitted jobs, so please 
make sure that you do not have jobs running at that time.
We will send an email around as soon as the cluster is up and running again.

We apologize for any inconvenience!

All the best,

Marius
