+{<h4 className="custom-header"> Per-instance external access annotations </h4>}
+
+When using `LoadBalancer` or `NodePort` external access, you can set annotations
+globally via `externalAccessConfig.dataInstance.annotations` and
+`externalAccessConfig.coordinator.annotations`. These apply to every external
+Service of that type.
+
+If you need different annotations per instance — for example, to assign unique
+DNS hostnames via `external-dns` — use the `externalAccessAnnotations` field on
+individual entries in `data[]` or `coordinators[]`. Per-instance annotations are
+merged with the global annotations, and **per-instance values take precedence**
+when the same key appears in both.
+
+```yaml
+externalAccessConfig:
+  dataInstance:
+    serviceType: "LoadBalancer"
+    annotations:
+      service.beta.kubernetes.io/aws-load-balancer-scheme: "internet-facing"
+
+data:
+  - id: "0"
+    externalAccessAnnotations:
+      external-dns.alpha.kubernetes.io/hostname: "data-0.memgraph.example.com"
+    args:
+      - "--management-port=10000"
+      - "--bolt-port=7687"
+  - id: "1"
+    externalAccessAnnotations:
+      external-dns.alpha.kubernetes.io/hostname: "data-1.memgraph.example.com"
+    args:
+      - "--management-port=10000"
+      - "--bolt-port=7687"
+```
+
+In this example, each data instance's external Service gets the shared
+`aws-load-balancer-scheme` annotation plus its own unique `external-dns`
+hostname.
