Hi Paul,

It’s possible the demo server is experiencing downtime.  Do you have other installs on your Cloud WordPress.  If so, do these sites display?  If all but this site is functioning properly we can narrow the issue down to the specific demo domain.

It’s possible our Cloud WP platform is experiencing issues at this time and I will check with our devs on your behalf to see if that might be the issue.

Thank you for your patience and we hope to have a resolution for you soon.
