S3 export delivery permissions - Resolved

Resolved after 7 hours 29 minutes, on September 9, 2026.

resolved Sep 11, 2026, 12:19 AM UTC

Some S3 export files delivered between September 9 at 20:32 UTC and September 10 at 04:01 UTC were missing the bucket-owner-full-control permission, which prevented affected customers from reading them. The issue is resolved. Exports moving forward and outside this timeframe are not impacted. No data was lost. For impacted files in the affected timeframe, set your bucket's Object Ownership to Bucket owner enforced (disable ACLs), if compatible with your bucket access requirements. If you have questions or continue to experience issues, please submit a support request.
