 Eiger is an Alps cluster that provides compute nodes and file systems designed to meet the needs of CPU-only workloads for the [HPC Platform][ref-platform-hpcp].
 
 !!! under-construction
-    This documentation is for `eiger.alps.cscs.ch` - an updated version of Eiger that will replace the existing `eiger.cscs.ch` cluster.
-    For help using the existing Eiger, see the [Eiger User Guide](https://confluence.cscs.ch/spaces/KB/pages/284426490/Alps+Eiger+User+Guide) on the legacy KB documentation site.

-    The target date for full deployment of the new Eiger is **July 1, 2025**.
+    This documentation is for the updated cluster `Eiger.Alps` reachable at `eiger.alps.cscs.ch`, that has replaced the former cluster as of June 30 2025.
+    The previous [Eiger User Guide](https://confluence.cscs.ch/spaces/KB/pages/284426490/Alps+Eiger+User+Guide) is still available on the legacy Knowledge Base.

 ### Compute nodes
 
-!!! under-construction
-    During this Early Access phase, there are 19 compute nodes for you to test and port your workflows to the new Eiger deployment. There is one compute node in the `debug` partition and one in the `xfer` partition for internal data transfer.  The remaining compute nodes will be moved from `eiger.cscs.ch` to `eiger.alps.cscs.ch` at a later date (provisionally, 1 July 2025).
-
-Eiger consists of 19 [AMD Epyc Rome][ref-alps-zen2-node] compute nodes. 
-
-There is one login node, `eiger-ln010`. 
-
-[//]: # (TODO: You will be assigned to one of the four login nodes when you ssh onto the system, from where you can edit files, compile applications and start simulation jobs.)
