We are currently investigating an issue where streaming transcription sessions using multi-channel audio (stereo or more channels) are failing to return transcriptions. Sessions using standard single-channel audio (mono PCM16 at 16kHz) are not affected. Our team has identified the root cause and a fix is in progress

The event was momentary and lasted only for a small number of requests in a duration less than 30 seconds. It's unlikely that any customer has noticed a degradation in TaT for any service. Streaming API connections may have been terminated by the server or partial/final hypothesis delayed by up to a minute during the event. If users are following our guidance and buffering audio locally and attempting to reconnect to the server when a server side termination is initiated, impact to end users would have been minimal.
We are continuing to investigate the underlying cause to prevent any future disruptions such as these.

Our records indicate that there was an internet connectivity outage which lasted on our service from approximately 7:20am to 7:50am on December 15, 2021. AWS corroborates this with their own status messages. Because this was a partial internet connectivity outage, some requests continued to resolve during this period.
From AWS Service health page on December 15 2021:
7:43 AM PST We are investigating Internet connectivity issues to the US-WEST-2 Region.
8:01 AM PST We have identified the root cause of the Internet connectivity to the US-WEST-2 Region and have taken steps to restore connectivity. We have seen some improvement to Internet connectivity in the last few minutes but continue to work towards full recovery.
8:14 AM PST We have resolved the issue affecting Internet connectivity to the US-WEST-2 Region. Connectivity within the region was not affected by this event. The issue has been resolved and the service is operating normally.
12:14 PM PST Between 7:14 AM PST and 7:59 AM PST, customers experienced elevated network packet loss that impacted connectivity to a subset of Internet destinations. Traffic within AWS Regions, between AWS Regions, and to other destinations on the Internet was not impacted. The issue was caused by network congestion between parts of the AWS Backbone and a subset of Internet Service Providers, which was triggered by AWS traffic engineering, executed in response to congestion outside of our network. This traffic engineering incorrectly moved more traffic than expected to parts of the AWS Backbone that affected connectivity to a subset of Internet destinations. The issue has been resolved, and we do not expect a recurrence.
