Wiki blackout is now in effect.
Any topic is redirected towards a page harboring these words:
Imagine a World
Without Free Knowledge
For over a decade, we have spent millions of hours building the largest encyclopedia in human history. Right now, the U.S. Congress is considering legislation that could fatally damage the free and open Internet. For 24 hours, to raise awareness, we are blacking out Wikipedia.
A link has also been provided describing and answering general questions on the situation.

If you still want to use wiki however:
Is it still possible to access Wikipedia in any way?
The Wikipedia community, as part of their request to the Wikimedia Foundation to carry out this protest, asked us to ensure that we make English Wikipedia accessible in some way during an emergency. The English Wikipedia will be accessible on mobile devices and smart phones. Because the protest message is powered by JavaScript, it's also possible to view Wikipedia by completely disabling JavaScript in your browser.
