## From the sources

Type: Maintenance
    Duration: 3 hours and 27 minutes

    Affected Components: Predictions Trading API (CLOB)
    Sep 2, 04:57:30 GMT+0 - Completed - Maintenance has completed successfully. Sep 2, 04:35:36 GMT+0 - Identified - We are currently in cancel-only mode. We will remain in cancel-only mode for at least 10 minutes before re-enabling trading. Sep 2, 03:59:27 GMT+0 - Identified - The DB maintenance is in final stages. We will perform internal checks after and enter post-only mode shortly after. Sep 2, 02:51:57 GMT+0 - Identified - The DB clean up is taking longer than initially estimated and trading will remain paused. We estimate another hour, but will update with a more concrete ETA as soon as we have it. Sep 2, 01:30:01 GMT+0 - Identified - Maintenance is now in progress Sep 2, 01:09:23 GMT+0 - Identified - Trading will be paused at 01:30 UTC, Wednesday, September 2 for approximately 1.5 hour. We are working with AWS 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.
