> DNS errors are common during testing due to typos or misconfiguration. They can also occur in production, as some transient DNS issues occur from time to time.
> 1) Let's investigate if we can distinguish between the two and fail fast for the test issues, but continue to have retry logic for the transient DNS issues in production.
> 2) Let's improve the error handling of DNS failures, so the user has an actionable error message.
