Subdomains not working since changing data center region

Hi

 

I previously had my domain on the America's data center. I changed this region to Europe last week and now my subdomains set up in cPanel are not working. When I go to the subdomains, it says;

 

Future home of something quite cool.
If you're the site owner, log in to launch this site
If you are a visitor, check back soon.

 

The subdomains are still visible in cPanel pointing to folders.

 

Thanks
