Engineers have scaled out services and this has partially mitigated the impact; the count of impacted subscriptions has been reduced.  However, some customers may continue to experience alerting failures from Log Analytics Metrics Alerts in the West Europe region.  We still do not have an estimate for when the system will be fully recovered.
