7. identified Oct 21, 2026, 06:31 PM UTC

   We've identified the cause of the delays in build logs appearing in the Netlify UI as an issue with an upstream service provider, who is working on a fix

8. identified Oct 21, 2026, 07:42 PM UTC

   We continue to work with our upstream service provider on the delays in build logs appearing in the Netlify UI.

9. monitoring Oct 22, 2026, 05:42 AM UTC

   The upstream provider applied a fix at 3:30 UTC and we are monitoring system health. We are able to ingest build logs at full throughput but we have hours of backlog that we need to process.

10. monitoring Oct 22, 2026, 06:17 AM UTC

    We are still monitoring the build log ingestion backlog. We will post our next update at 7:30 UTC, or sooner if anything changes.

11. monitoring Oct 22, 2026, 07:41 AM UTC

    Build log processing continues at full throttle and we estimate backlog to be cleared by 9:00 UTC. We’ll post next update at 8:45 UTC.

12. monitoring Oct 22, 2026, 08:59 AM UTC

    As of 08:45 UTC, we are still processing the backlog of build logs at full throttle. Some partitions have completed backlog processing, but others still have backlog pending. As a result of this partial processing, customers may experience intermittent availability until the full backlog is processed. Some build logs may be available, and others not. Real-time build logs should be working as expected. The new ETA for backlog processing is 10:00 UTC. We will provide our next update at 10:00 UTC.

13. monitoring Oct 22, 2026, 09:35 AM UTC

    We have completed processing the Build Logs backlog. All customers should now have a consistent experience when viewing both historical and new Build Logs in the UI. We believe customer impact has ended. We will continue to closely monitor the situation for any signs of recurrence.

14. resolved Oct 22, 2026, 10:28 AM UTC

    The issue causing delays in build logs appearing in the Netlify UI has been resolved.
