I think the Canon Rumours guy will have to find another host to his website, and a non-american one.
Many of us have temporarily blocked our own sites for the day to protest the proposed SOPA and PIPA legislation. Kudos to him for taking part - it costs him real advertising affiliate income to take this stand.
The blockage gets handled in various ways: Some sites will redirect to another site with PIPA/SOPA information, some will let you click through to the site after seeing the initial message (as on Canon Rumors), some will block you the first time but not thereafter, others will only block for a few hours, etc.
