Currently, when Sidecar is down for any reason, any access (via git commands or via the browser) to repositories results in a RepositoryOfflineException, arguably rendering the node useless for serving the vast majority of requests.

As such, requests should not be routed to a node in such a state, and for a load balancer to detect that, the /status endpoint should return ERROR when Sidecar is not running (or repositories are offline for any other reason).
