We are experiencing high device streaming latency on this affected cluster. Some impact may be user visible, such as: - A delay in processing streamed device data. Some events such as "Device stopped streaming" or "Streaming Latency Breached Threshold" may fire as a result of this. In this case, the device updates are behind schedule and will be processed with some delay during the impact window. - There may be some stale data, or sporadic timeouts viewing parts of the UI. - Some provisioning features may be delayed or timeout due to the high latency. We are currently investigating the issue and working on mitigation. Thank you for your patience.
