Question

While creating user using microsoft graph,it was working fine yesterday but now I am getting the error below. I re-activated the subscription.

   "error": {
        "code": "Directory_ReplicaUnavailable",
        "message": "The preferred replica is unavailable. Please retry your request.",
        "innerError": {
            "request-id": "19030bd0-0aad-49cf-9d40-6fcb7fb4360e",

        }
    }
