Oziexplorer web site..help something weird here

For the last 24 hours I have been unable to access the Oziexplorer web site.......Despite accessing through my favourites as per normal (and so no misspelling)....or typing in the top bar exactly....or using google search and clicking on the link.....all I can get is Oops!..this link is broken

when I checked using my laptop same thing happens..only common link there is the Next G wireless modem router (bigpond) ..so far I have

used the tools menu on IE 7 and deleted all search history/ cookies./ add on etc. Hit the F5 key to refresh.....turned the computer off and on again, turned the modem off and on and waited over night

still the same result...........I cannot understand why as a previous helpful post yesterday informed me that the site was working!

Is anyone able to where this damn gremlin is lurking in my network / router etc and how to resolve this? all other web sites are working fine ...just not the one I want!...never experienced anything like it before

thanks
