-??? note "Maintenance "
-
-    The GPU cluster Alpha Centauri (Partition `alpha`) will be shut down from November 27 to
-    December 10 for works on the power supply infrastructure. These additional changes are planned:
-
-    * update the software stack (OS and applications, firmware, etc)
-    * change the ethernet access (new VLANs),
-    * integrate 5 new (identical) nodes.
-
-    After this maintenance, Alpha Centauri will then reappear as stand-alone cluster that can be
-    reached via `login[1,2].alpha.hpc.tu-dresden.de`.
-
-    **Changes w.r.t. filesystems:**
-    Your new `/home` directory (from Barnard) will become your `/home` on Romeo, Julia, *Alpha
-    Centauri* and the Power9 system. Thus, please [migrate your `/home` from Taurus to your **new**
-    `/home` on Barnard](barnard.md#data-management-and-data-transfer).
-
-    For now, Alpha Centauri will not be integrated in the InfiniBand fabric of Barnard.
-    With this comes a dire
-    restriction: **the only work filesystems for Alpha Centauri** will be the `/beegfs` filesystems.
-    `/scratch` and `/lustre/ssd` are not usable any longer. Please, prepare your stage-in/stage-out
-    workflows using our [datamovers](../data_transfer/datamover.md) to enable the work with larger
-    datasets that might be stored on Barnard’s new capacity filesystem `/data/walrus`.

 ## Romeo
 
 The cluster `Romeo` is a general purpose cluster by NEC based on AMD Rome CPUs.
