These claims seem accurate: websites for prominent UK newsrags The Sun, The Times, and News International are all inaccessible at the time of writing. Earlier today The Sun homepage redirected to a false report of Rupert Murdoch’s death. Later it directed visitors to the LulzSec twitter feed.
Currently News International is either being shut down by hackers or voluntarily pulled the plug on it's own servers to prevent additional hacks. One certainty is that today billionaire media tycoon Rupert Murdoch got OWNED. Let that be a lesson to all with the wealth, power, and influence to spin lies and promote an agenda while claiming to be "Fair and Balanced."
