Sony hack: Internet reacts to North Korea web shutdown

Social media users are offering their own ideas on what was behind North Korea's internet outages as debate rages over who ordered a cyber attack on Sony Pictures.

The outages came just days after president Barack Obama warned the US would respond "proportionately" to the hack, which he said the North Korean government was responsible for.

On Twitter, many users were suggesting that the United States was behind North Korea's internet shutdown.

Other Twitter users were unconvinced that the United States had caused North Korea to go offline, saying their motivations did not line up.

Some simply used the news as an opportunity to poke fun at the Asian nation.
