Update timeline

  1. identified Jun 18, 2026, 08:11 PM UTC

    The team has identified a regression causing send requests to be stuck in a queued state. We have initiated a rollback to quickly resolve the issue. More updates to follow

  2. identified Jun 18, 2026, 08:35 PM UTC

    The rollback deploy will land in about 30 minutes.

    The team has identified that the most recent deployment was not the cause of the regression. The team is still working on identifying the root cause. Messages will not be dropped, and they will be processed once the fix is out.
