YackTrack will be taken offline soon as the servers are being patched by my ISP. I have been told that they will be offline tonight from 12AM GMT-7 until 5AM GMT-7.
I apologize for any inconvenience this may cause. I will update this post when I receive a notice that the servers are available again.
UPDATE: The servers are up again and YackTrack is back to normal. Thank you for your patience.
