Hmm, I just tried to check out his site for some of his older articles and it seems to be down. If you watch the status bar at the bottom, the URL is http://www.siyamiozkan-mavideniz.org

This should be interesting…

Update: Bloglines returns this for his feed:

Bloglines has encountered an error trying to fetch the latest version of this feed. Bloglines handles errors automatically, no action is required by you. The error was:

The feed URL returns a page that does not look like an RSS feed. This can be caused by the feed URL being incorrect, or it can be caused by a configuration issue with the server hosting the feed. If this error continues, you should check the feed URL and, if it is wrong, subscribe to the correct URL.

 Update: Apparently it’s been this way for a little bit according to Ramblings from the Marginalized.

Update: It looks to be a redirection as even his feed is going to the listed site. Popup blockers and AV armed, I checked out the above link and it looks like ISKORPTIX (link is safe, an article on the biggest hack he did in 2006) is responsible.

Update: Looks like Stephen Fung and Leo Chiang’s sites are down as well according to RFTM.

Update: Looks like the site is completely down now after HMTKSteve of RFTM gave John a call to inform him of the hack.

Final Update: His site is completely down at the moment to clean up the mess I’m sure. Heading to bed as I had intended to do before… I’d wager it will be back up shortly.

Final (for real) Update: The site is fully back up and serving content again.
