    We are currently investigating this incident.

    Trading will be paused right now for approximately 30 minutes. We are working to apply a final fix to their internal DB issue for the root cause of the database replica lag, which includes several database tuning operations. 

    There will be a 5 minute cancel-only mode that will be announced before trading is resumed, and any changes in ETA will be announced as soon as we have them.
