# Health

> Tri-state health check used by load balancers and monitoring systems.

The Health endpoint provides a simple, unauthenticated liveness check for WireSocket Data Plane nodes. It is used by load balancers (e.g., Bunny DNS) and monitoring systems to determine whether a node should receive traffic.

***

## Endpoints

Both paths return the same response:

```http theme={null}
GET https://{region-code}.wiresocket.net/health
GET https://{region-code}.wiresocket.net/
```

***

## Authentication

**None required.** This endpoint is publicly accessible to support load balancer health probes.

***

## Response

The endpoint returns one of two HTTP status codes based on the node's internal state:

| HTTP Status | State                     | Description                                                                                   |
| :---------- | :------------------------ | :-------------------------------------------------------------------------------------------- |
| **200**     | `HEALTHY`                 | The node is operating normally and can accept new connections.                                |
| **503**     | `DEGRADED` / `OVERLOADED` | The node is under pressure or Redis is unreachable. Load balancers should route traffic away. |

### Response Body

```json theme={null}
{
  "status": "healthy",
  "timestamp": "2026-03-04T06:00:00.000Z"
}
```

| Field       | Type   | Description                                                 |
| :---------- | :----- | :---------------------------------------------------------- |
| `status`    | string | Current node state: `healthy`, `degraded`, or `overloaded`. |
| `timestamp` | string | ISO 8601 UTC timestamp of the check.                        |

***

## Rate Limiting

This endpoint uses the `HEALTH` rate limit policy, which is more permissive than standard endpoints to allow frequent polling by infrastructure services.
