After: Since 2026-09-22 16:50 PT (23:50 UTC), we have been experiencing an issue with automated data exports to all export destinations. This only affects exports that filter events before export. Customers using export destinations may notice that new data is not being delivered to your destination.
Our team is actively investigating the source of the issue and working to restore exports as quickly as possible. No data will be lost; once resolved, exports will resume and backfill automatically. No customer action is needed at this time.

After: We're still working to confirm that automated data exports are getting back to normal. No customer action is required at this time.
Before: not present
After: We've identified that this issue can also affect exports without event filtering, due to backlog from the affected jobs. Previously we noted impact was limited to exports with event filtering, we're updating that guidance as we've confirmed broader impact.
If you're experiencing delayed or stalled exports to S3, BigQuery, or Snowflake, this may be related, even without filtering configured.
We're still working to confirm exports are getting back to normal. No customer action is required at this time.
Before: not present
After: We're seeing recovery across most affected export jobs, and most customers should now see exports returning to normal. A subset of jobs are still catching up, and we're continuing to monitor until all exports are fully recovered.
No customer action is required at this time.
Before: not present
After: Automatic export jobs are running again for most customers. Recovery looks on track, though we're still confirming full resolution and continuing to monitor closely.
No customer action is required at this time
