+## Connection Status
+
+#### Type definitions
+
+```yml
+types:
+  ConnectionStatus:
+    type: enum
+    values: [Disconnected, PartiallyConnected, Connected]
+    description: "Used to identify health of the operating node"
+```
+
+#### Extended definitions
+
+`Disconnected` indicates that the node has lost connectivity for message reception,
+sending, or both, and as a result, it cannot reliably receive or transmit messages.
+
+`PartiallyConnected` indicates that the node meets the minimum operational requirements:
+it is connected to at least one peer with a protocol to send messages ([LIGHTPUSH](https://github.com/vacp2p/rfc-index/blob/main/waku/standards/core/19/lightpush.md) or [RELAY](https://github.com/vacp2p/rfc-index/blob/main/waku/standards/core/11/relay.md)), 
+one peer with a protocol to receive messages ([FILTER](https://github.com/vacp2p/rfc-index/blob/main/waku/standards/core/12/filter.md) or [RELAY](https://github.com/vacp2p/rfc-index/blob/main/waku/standards/core/11/relay.md)),
+and one peer with [STORE](https://github.com/vacp2p/rfc-index/blob/main/waku/standards/core/13/store.md) service capabilities,
+although performance or reliability may still be impacted.
+
+`Connected` indicates that the node is operating optimally,
+with full support for message reception and transmission.
