What does an Internet strike look like? You’re about to find out.

Wikipedia, Reddit, BoingBoing and even ICanHazCheezburger have joined hundreds of other websites in a pledge to go dark Tuesday night to protest the Stop Online Piracy Act (SOPA) and the Protect IP Act (PIPA) — two anti-piracy bills that are currently making their way through Congress.

“This is an extraordinary action for our community to take,” said Wikipedia founder Jimmy Wales in a statement Monday announcing Wikipedia’s decision to go dark. “While we regret having to prevent the world from having access to Wikipedia for even a second, we simply cannot ignore the fact that SOPA and PIPA endanger free speech both in the United States and abroad, and set a frightening precedent of Internet censorship for the world.”
