Microsoft has some influence on the .ms TLD. We settled on a .ms domain for a project, and ultimately scraped it in favor of our current name because we couldn’t get Route53 to pick it up. Initially I thought it was an AWS bug and even reported it to them to no avail. I did some more digging and discovered Microsoft was using .ms for doc sites, and it started to add up. I believe AWS is intentionally not routing traffic to TLDs associated with Microsoft.
