I can no longer access the website on my mobile. Having done a whois lookup, it appears that there may be an issue with the domain

Your selected domain name is a domain name that has been cancelled, suspended, refused or reserved at the Point ML Registry.
I suspect it's only a matter of time until the site goes down for everyone.
@phonics, did you or @Baz register the domain?
