  1. investigating Apr 27, 2026, 10:04 PM UTC

    It seems to be only in AWS clusters for now. We have a workaround while we investigate.

  2. investigating Apr 27, 2026, 10:05 PM UTC

    We are continuing to investigate this issue.

  3. resolved Apr 28, 2026, 12:16 AM UTC

    We rolled back a change we made to our authentication system. Any image pushes or config changes to a deployment that occurred after our rollback caused the deployment to fix itself, which is why so many people found their 403s resolved themselves after some time.
