Anonymous has called for an Internet blackout for April 22nd in response to the US House of Representatives passing the Cyber Intelligence and Protection Act (CISPA) on Wednesday. The collective is asking all websites owners to black their site out and replace site content with a message telling people about CISPA and why it's bad.
For those of you wanting to participate but not sure what to do, I've created a simple website page that you can download and use. Simply grab the script from my GitHub account by clicking here, upload it to your server, and either replace your main page with the new page or redirect your main page to blackout.html.
CISPA is dangerous and has to be stopped. We've beat it before and we can beat it again. We just need to stand together in solidarity.
