Processing times have continued to be in the normal range, so we are now marking this issue as resolved.
We have continued to work to resolve this issue and are now seeing processing times return to the normal ranges, but we are continuing to monitor to ensure good performance.
We are still working to fully resolve the issue, but we are seeing improvement in turnaround times for the Universal-3 Pro models.
We are currently experiencing issues that are resulting in longer-than-usual processing times for Async STT requests using our Universal-3 models. We are working to resolve this issue as quickly as possible and will provide further updates as soon as we can.

Follow AssemblyAI
Your coding agent knows when AssemblyAI is down, and tells you when a failure is theirs, not yours. You can also get AssemblyAI incidents in a feed reader or in Slack.
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.
Add it as a remote MCP server named "outages" at https://outages.cc/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.
Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "assemblyai" and tell me if AssemblyAI has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.Paste this into any coding agent. It adds the server with its own MCP setup.
