Hackers have targeted the web site of the ACT Chief Minister Jon Stanhope.
Constituents going to the www.chiefminister.act.gov.au are redirected to hacking archive site Zone-H.org.
The message on the Chief Minister's site says: "Fatal Error was here ohh yeahh let's go! irc.gigachat.net #Ferror".
The site has been offline since this morning.
According to Zone H, the site runs the Apache Web server on top of Linux.
While the homepage URL does not work, links such as http://www.chiefminister.act.gov.au/ministers.asp?title=Ministers are still active.
Interestingly, any links such as media releases and speeches pertaining to other ministers such as Ted Quinlan, Simon Corbell, Katy Gallagher, and John Hargreaves all work.
Leah De Forest, a spokesperson for the Chief Minister said the police had been notified. She said the Chief Minister's IT department was working to try and get the site back as soon as possible.
There are no clues to the reason for the hack.
However, Stanhope has expressed dissatisfaction at the federal government's anti terror laws which it has tried to quickly pass through parliament. Several weeks ago he posted information about the laws on his site.
