+# Infra/node decommissioning
+
+## High overview
+
+This is an overview of the needed tasks to perform when we want to remove a node from our infra : 
+
+  * Delete/reinstall the (virtual) machine (cleaning up)
+    * If hosted within Red Hat DC, update [internal ip inventory](https://docs.google.com/spreadsheets/d/1K-aewLJ17z3pRC6K5qyBRJYtNXy1WcxRSVwPkGf4NXQ) (Obviously need RH SSO and permission)
+  * Remove from [DNS](/infra/dns/) (public of internal, depending on the case)
+  * Remove it from Ansible inventory (and search for references for that node in case of)
+  * Remove it from Zabbix monitoring
+
