"Twitter, Amazon, Paypal and Spotify all experienced crippling problems following the strike, going offline for hours.
Later, Julian Assange's infamous website – famed for its exposure of the Afghan war diaries in 2010 – tweeted: “Mr Assange is still alive and WikiLeaks is still publishing.
“We ask our supporters to stop taking down the US internet. You proved your point.”
The account followed this up with another tweet reading: “The Obama administration should not have attempted to misuse its instruments of state to stop criticism of its ruling party candidate.”
The coordinated strike comes after Assange – barricaded in the Ecuadorian embassy in London since 2012 – claimed the US government last week silenced him by cutting off his internet connection.
Connection to dozens of sites was lost following an attack from “millions” of internet users around 6AM Eastern Time (11AM GMT), according to Internet service company Dyn."
