What is the default timeout setting in CloudFront, and how can I adjust it?

The default origin timeout is 30 seconds. You can adjust this in your CloudFront distribution settings under 'Origin Settings' -> 'Origin Timeout (seconds)'. Increasing the timeout can help if your origin takes longer to respond, but excessively long timeouts can mask underlying performance issues. A range of 30-60 seconds is often a good starting point for adjustments.
