Speed Test - My Interior Keeps Failing on KDP When Uploading

If you have a slow internet connection your interior could fail (possibly cover as well, but less likely due to it is usually a smaller size). Your upload speed needs to be usually at least 3 MBPS and probably closer to 5 MBPS. (For the Book bolt Studio, these are probably the same needed as minimum to not have issues while working in the Studio).

To test your speed go to Google and type in: Speed Test

You will see below your search term this from Google:

Click on the "Run Speed Test"

Let it run until it is complete. The upload speed is on the right side and the one you should look at to see what your speed is and could possibly explain why your upload is failing to KDP.
