is there any error messages in your chatbot's logs ? don't want to throw the problem on somebody else but when OpenAI goes down, we're unfortunately impacted. most of the latency and downtime in live bots are coming from OpenAI. they really improved recently but they still experience scaling issues a few times a week

scalability wise, we made some upgrades on our side in the last week or so; each deployed bots can process up to 10 messages / second
