Sites across the internet suffer outage after cyberattack

Sites across the internet had problems on Friday morning
following a cyberattack on a major internet management company.
Dyn announced on Friday morning that it has been the
subject of a cyberattack that then caused major problems for numerous websites.
People have reported issues with Twitter, Spotify, SoundCloud, Vox Media sites,
Airbnb and numerous other sites.
The attack was resolved as of 9:20 a.m. EST, Dyn said.
Writing on its website, Dyn said that starting at about
7:00 a.m. EST, the company "began monitoring and mitigating a DDoS attack
against our Dyn Managed DNS infrastructure. Some customers may experience
increased DNS query latency and delayed zone propagation during this time.
Updates will be posted as information becomes available."
DDoS stands for "distributed denial of service"
and is a common tactic used by hackers to take down internet-connected servers.
In a DDoS attack, malicious users build a network of computers that then send
massive amounts of traffic to particular servers with the goal of denying the
use of those servers to other users, according to Cisco.
The attack mainly affected the eastern United States, Dyn
said.
The source of the attack was not immediately apparent.
The attack comes at a time of heightened tension over
recent cyber attacks, with the US claiming it would hit back at Russia after
accusing the country of hacking the Democratic National Committee.
Hacker News first noted Friday's "massive Dyn DNS
outage." The site said that if sites reported as down were working for
some users, those users' machines have likely cached the DNS response for those
sites.
Internet service firm Level 3 communications found that
the outage primarily affected the east coast of the U.S.
