Hacktivist group Anonymous took control of the U.S. Sentencing Commission website Friday, January 25 in a new campaign called "Operation Last Resort."
The first attack on the website was early Friday morning. The second - successful - attack came around 9pm PST that evening.
By 3am PST ussc.gov was down (it has since been dropped from the DNS), yet as of this writing the IP address (126.96.36.199) still returns the defaced site's contents.
