We will be performing scheduled maintenance on our Streams API, which will temporarily affect the history replay feature. During this window, replaying stream history will be unavailable; however, no data or history will be lost.

All other Streams API services will remain fully operational throughout the maintenance.

Expected duration: 1–3 hours. Once completed, history replay will be restored automatically.
