Please be advised that due to a system issue, matching on the Cboe C2 Options Exchange order book in options classes IWM - JNJA was unavailable between 09:30:14 and 09:31:03 ET.
All open quotes in the affected range during the outage were cancelled. Open orders would have also been cancelled unless requested to be kept live based on port configuration. Matching in the affected range has been restored and all systems are now operating normally.
