The Stop Online Piracy Act (SOPA) hit a snag over the weekend when the White House stepped in to speak out against it. Not long before that happened, both SOPA and the Protect IP Act (PIPA) had parts that were being reconsidered, thanks in part to public backlash. PIPA is still up for vote, but SOPA has been stalled for the time being. The White House said it cannot condone any legislation that "reduces freedom of expression, increases cybersecurtiy risk, or undermines the dynamic, innovative global Internet." The White House has issues with the DNS-blocking provisions in SOPA, which is one of the things being looked at in both it and PIPA. Opposition has been extremely vocal from the Internet communities, with several sites like Reddit, Minecraft, and Firefall going dark on Wednesday the 18th in protest. Even Wikipedia's English version has joined the blackout, which should be extremely problematic for anyone needing to get some information on Wednesday.
PIPA is still under consideration by the Senate, while SOPA will more than likely appear later in a rewritten form.
