Update 1:53 p.m.: Comments from citizens have been flooding congressional office websites today. So much so, Gizmodo reports, that some Senate sites are actually crashing. Affected websites include Mark Begich (D – AK), Barbara Boxer (D – CA) and Patrick Leahy (D – VT).

So, it may not a complete Internet blackout and some sites are being more vigilant about their protest of the House‘s proposed Stop Online Piracy Act and the Senate’s Protect Intellectual Property Act, but it seems to be the most cohesive protest on the Internet to date.

These two pieces of legislation, many free Internet supporters believe, would lead to online censorship and hamper the entrepreneurial atmosphere on the Internet. Even the White House has spoken out against the legislation.

Here’s what the blackout/protest looks like on participating sites:

Wikipedia will be dark for 24 hours, but see the end of this post to a link for loopholes around the blackout if you simply must do some fact checking with the site today.

Google is still fully functional today, but it did blackout its logo in protest on its primary and secondary search pages.

Syracuse University School of Informational Studies went dark today as one of many universities protesting the legislation.

Don't be alarmed when you want to search for treasure out of someone else's trash on Craigslist today. The site will only be black for 10 seconds before coming up.

The popular blog BoingBoing, among many others, joined in.

If you really must, MUST look at Wikipedia today — we know that spring semesters are just starting — check out this Blaze article about some loopholes that will get you in.

Here’s a list of other sites (although not a complete list) protesting the legislation.
