Vapifault worker not available issue coming . Can anyone please check and treat this as high priority

We're you talking to me?

Hi, Thank you for providing all IDs, they are very helpful. I reviewed and found that the calls ended with vapi worker related errors. This is due to an outage we had yesterday with Vapi workers which has been resolved right now. You can find more information about it here: [https://status.vapi.ai/incident/831494](https://status.vapi.ai/incident/831494). We apologize for any inconvenice this might have caused you. Please let me know if you are still facing this issue.

I changed my API traffic channel setting from daily to weekly. Will this avoid this kind of failure in the future? Was there any benefit to my customer that I changed that setting?

Hi @Michael, Weekly channel is much more stable than the daily channel. So you can expect a lot less issues with weekly channel in general. However I cannot guarantee that there wont be any downtime on the weekly channel. But I would highly recommend using weekly channel if you are dealing with a large amount of calls.

It's only a thousand calls a month, but I switched to Weekly. Why is the default Daily if it is less reliable?

Hi @Michael, The daily channel is default because this receives frequent updates compared to the weekly channel. Due to being more upto date, it is set as the default channel.
