The full scope of North Korea's private internet has been revealed after the country accidentally gave people outside of the country brief access to it.

The government-controlled internet is a lot smaller than was initially believed, containing just 28 websites in total, including an insurance company, sports website and site containing culinary information and recipes, according to information posted to GitHub.

Previous reports had suggested the North Korean internet was significantly larger, with as many as 5,500 websites. But when access to the country's web was briefly available this week, the GitHub users found just 28 North Korean domains.
