Outage incident: CMN-201: Service Temporary Unavailable

There appears to be some type of outage right now with web socket subscriptions.

Here's what I'm seeing:

POST to https://platform.devtest.ringcentral.com/restapi/v1.0/subscription

With body:

{
  "eventFilters": [
    "/restapi/v1.0/account/~/extension/~/presence"
  ],
  "deliveryMode": {
    "transportType": "WebSocket"
  }
}

Returns:

{
    "errorCode": "CMN-201",
    "message": "Service Temporary Unavailable",
    "errors": [
        {
            "errorCode": "CMN-201",
            "message": "Service Temporary Unavailable"
        }
    ]
}

Hoping a RC engineer can resolve this soon. Thanks!
