autodiscover cname record not working

The autodiscover cname record for Exchange online (office 365) does not work. When I ping the autodiscover.mydomain.com location I get no response. Outlook cannot find either. Office 365 says it is configured correctly.

Any thoughts?

The CAME shows up in a dig:

The ping result is:

Maybe it just needed some more time to propagate.
