DNS Troubleshooting?

This video covers a troubleshooting scenario where clients experience intermittent performance issues, or as they call it, “stuttering”.

The point of the video is to review some troubleshooting best practices where we ‘validate and verify’ what we are told, document any observations, test and document your results.

So even though this looked like a DNS issue, after troubleshooting, it ended up being a routing issue. As I mentioned at the end of the video, you should always perform a “routing audit” to document, confirm and learn where packets route in your environment.
