If today you have detected that WhatsApp, Spotify or Twitter are having trouble running, look no further. They are having falls. Not only these services, but other online services as well. What has happened? A DDoS attack on DynDNS has knocked down medium internet.
Middle internet down
A DDoS attack produces a denial of service crash. What is this? We have explained it other times. Basically, it involves repeatedly attacking a certain element until it is unable to respond to so many requests. In a simplified way, it can be said that you try to use a service so much that it becomes saturated and deactivated, it generates overload problems. On a web page, it could be a higher number of hits than it can handle. In a messaging app it could be sending more messages than the service can handle. But, how is it possible that this attack has affected services as diverse as WhatsApp, Spotify or Twitter? Well, very simple, because actually DynDNS services have been attacked.
The DNS servers are responsible for converting a name like spotify.com into its IP address. That is, they change the name we know to the real address of that server. DynDNS is one of the most extensive DNS servers in the entire network. And having been attacked, this has affected the proper functioning of services as diverse as WhatsApp, Twitter or Spotify.
WhatsApp down, even in Spain
Of course, it must be said that these services have not been dropped in a generalized and uniform way. The falls began in the United States, but little by little this problem has been affecting other regions. Users in Europe already report errors in WhatsApp. Some only have errors when sending images and videos, but not in messages. Other users are only experiencing erratic performance on services like Spotify or Twitter. Although this is also reaching dozens of other services such as PlayStation Network or Xbox Live among others, so it is rare that it has not affected you or will affect you in some way. What will have to be determined is who may have the intention of making half the Internet in half the world go down.
