After a 24-hour blackout, Wikipedia has returned to full working order but declared: "We're not done yet."
The site had blocked its content for 24 hours in protest at proposed anti-piracy legislation in the US.
The encyclopaedia said the site had been viewed 162 million times, with eight million people following instructions to contact politicians.
The protest led to eight US lawmakers withdrawing their support for the proposed bills.
Two of the bill's co-sponsors, Marco Rubio from Florida and Roy Blunt from Missouri, are among those who have withdrawn their support after "legitimate concerns".
But backers of the legislation, led by the Motion Picture Association of America (MPAA), described the action as an "irresponsible" publicity "stunt".
Wednesday's co-ordinated action was intended to raise the profile of the debate to those outside of the tight-knit technology community - an objective Wikipedia said had been met.
"More than 162 million people saw our message asking if you could imagine a world without free knowledge," the site said.
"You said no. You shut down Congress's switchboards. You melted their servers.
"From all around the world your messages dominated social media and the news. Millions of people have spoken in defence of a free and open internet."
Elsewhere, Facebook founder Mark Zuckerberg deemed the occasion worthy enough to post his first tweet in almost three years.
"Tell your congressmen you want them to be pro-internet," he wrote, linking to a longer statement on Facebook.
He continued: "We can't let poorly thought out laws get in the way of the internet's development.
"Facebook opposes Sopa and Pipa, and we will continue to oppose any laws that will hurt the internet."
Google, which urged its US visitors to sign a petition against the bills, said more than 4.5 million signatures had been gathered.
News Corporation chairman Rupert Murdoch, a vocal supporter of Sopa, continued to spar with users on Twitter.
He tweeted: "Seems blogsphere has succeeded in terrorising many senators and congressmen who previously committed. Politicians all the same." before asking: "On Sopa, where are all big film stars with many millions to lose ?"
