Twitter, Spotify, Reddit, Soundcloud and several other sites have been affected by a web attack.

All the firms are customers of a company called Dyn which they use to help users find their sites online.

In a statement on its website Dyn said the DDoS attack started early on Friday morning in the US and affected firms more in the east of the country. The initial impact of the attack made some sites harder to reach as queries sent to locate them took longer to process.

The incident marks a change in tactics as DDoS attacks are more typically aimed at a single site. Dyn acts as a directory service for huge numbers of firms that helps their customers keep global address books up to date with the location of their domains.

Richard Meeus, from security company NSFocus, said the attack showed how critical domain directory services were to the running of the net and how that they had often been "neglected" security-wise.

"It is treated as if it will always be there in the same way that water comes out of the tap and electricity is there when you switch it on," he said.

This morning, several sites were shut down due to a distributed denial of service (DDoS) attack on Dyn, a large domain name server. Sites affected include Twitter, Spotify, the New York Times, Reddit, Yelp, Box, Pinterest, Paypal and potentially a lot more. It seems as if this attack was focused on the east coast. Now Reuters is reporting that the US government is investigating it to see if it was a "criminal act."
