Further to my talk with TF about the website. It looks like someone at DYA it futzing with it:

http://www.dynamicfuel.com/product/faq.php

Note how in the second FAQ the font changes after the 3rd Jetstar as a tag has been accidently deleted. Seems like the reason for the site being masked may be genuine.

Hopefully Alex, or whoever is making the changes, will fix it before they let the front page go again on Friday.
