Try new SharePoint Admin Center

Yea, it is most definitely a demo page. But why does it show up in this customers tenant. That is the strange part. This customer is set to standard release but they have the "Try out the new SharePoint Admin Center" link on top right, and you click it, it takes you to what looks like the new admin center. It took me a while to notice it was a demo, but when I clicked on "Site Management" and I noticed the site owners of some of the sites, then I realized it was not real. That is why I was wondering if anyone else has seen this.
