Is there downtime when deploying agent updates to LiveKit Cloud?

[LiveKit-Community]

This question originally came up in our Slack community and the thread has been consolidated here for long-term reference.

Is there any downtime when deploying an agent to LiveKit Cloud?

Context: you have an agent in production taking business calls, and you want to deploy an update. Does the agent remain functional during the deployment?

[LiveKit-Community]

Running agents will drain and new calls will be load-balanced to new agents. There is no downtime for new calls.

See the drain timeout documentation:
