Hackers cut off internet in Liberia 

Liberia has been repeatedly cut off from the internet by hackers targeting its only link to the global network. 

Recurrent attacks have flooded the cable link with data, making net access intermittent.  

Researchers said the attacks showed hackers trying different ways to use massive networks of hijacked machines to overwhelm high-value targets.  

Experts said Liberia was attacked by the same group that caused web-wide disruption on 21 October.  

Those attacks were among the biggest ever seen and made it hard to reach big web firms such as Twitter, Spotify and Reddit.
