Perhaps it is being updated and they do not have a hosting test server available; therefore, the updates are being made in their production environment and they do not want others to see the updates before they are approved.
They do have a hosting test server...for all the same reasons as above...and the hosting developer put the security on the wrong site.

My guess is the last, but a check of the registration shows no assignment...yet. Unlikely then it means an acquisition of sorts. But really, I cannot imagine anything else that would be reasonable other than a re-branding of the company.
