## Updates from Stream
### 2018-08-08 01:09 UTC: resolved
Our distributed realtime cluster uses Redis (on Elasticache) for state management. A failover of the Elasticache cluster caused realtime to be unavailable for 7 minutes. This issue has been resolved and we're investigating why the failover took 7 minutes. This impacted customers using Stream's websocket, SQS or Webhook firehose systems.
