Forte Enterprise 1 has completed its planned maintenance ahead of schedule and is back online and processing jobs. It is currently operating in a degraded state due to unexpected system drift. In order to prioritize customer availability, we have opted to return the system to service now, rather than remain offline for further testing. We are actively investigating the source of the drift and will provide an update if there are any changes to the system status.
