Voiceflow servers very slow in the last 3 hours
Hello,
Anyone else having speed issues with their voiceflow agent?
Mine is in production and is much slower than usual.
Also the 3 dots that usually appear when Voiceflow is processing don't appear anymore.
I hope it is temporary

It’s possible you’re hitting a transient latency issue on the Voiceflow runtime rather than something specific to your project.
Here are a few quick checks:
• Status page – first thing to verify is whether Voiceflow is reporting an active incident or degraded performance: https://status.voiceflow.com
• Preview speed – open the project in Creator and run “Test” (or the voice prototype) from inside Voiceflow. If the delay is the same there, it confirms it’s runtime-side rather than your web-chat embed.
• LLM / API limits – heavy traffic or rate-limits on your selected model (e.g. OpenAI) will slow each turn. You can look at the “Logs” tab for the execution and see how long each step is taking.
• Concurrent sessions – if you’re near the session limit on your plan, new conversations have to wait for capacity, which can look like a long pause (docs: Troubleshooting voice → “Limits”).
• Cache / widget – if the 3-dot typing indicator used to show and no longer does, try a hard browser refresh (⌘/Ctrl + Shift + R). In most cases that resets a stale cache and the indicator returns. If Preview is fast but the live widget remains slow after these steps, capture an execution ID from the Logs tab and compare timestamps; long gaps usually point to the external LLM call or a downstream API rather than Voiceflow itself. Hope that helps narrow it down!
