Yay, all done!
The problems were indeed the DNS propagation, which has now completed, so the site should again be accessible worldwide
Cheers folks!

The process of moving Ballagroove is still in progress. There seems to be some problems with the DNS propagation, resulting in parts of the site still being referred to the old host.
Hopefully these issues should resolve themselves once this process completes.

Ballagroove is moving to a larger, better featured web host as part of the plan to improve the site. As a result the website and e-mail will be down for an unknown time while the DNS records propagate to the new server (this should be under 6 hours).
Thanks for your patience, please call back tomorrow!
