Apologies for any inconvenience caused. Impacted Cloud Regions & Services: AWS & GCP User Experience: We expect that the rate of failures for materializations and scheduled exports to be substantially decreased. Users should not need to manually sync their databases/schemas/tables anymore at this time, changes done in the warehouse should automatically show in Sigma again. Navigating newly-created connections should also be functional. Incident Start Time: Approximately 11:50 UTC April 20, 2023 Incident End Time: Approximately 12:30am UTC April 21, 2023 We will perform a root cause analysis (RCA) and publish our findings in a postmortem note to the Sigma Community site in coming days.
