A number of popular sites and services are down across the globe for many users of Twitter, SoundCloud, Spotify and Shopify, due to a sweeping outage of DNS provider Dyn as a result of a DDOS attack, according to a post on Hacker News.
Other sites which also experienced issues are Airbnb, Github, Freshbooks, Reddit, Heroku and Vox Media properties. Users who were accessing these sites might have success depending on where they’re located, as Asian and European users did not encounter any issues.
According to Dyn, the DDOS attack affecting its customers mainly impacting the U.S. East coast. Engineers are working on “mitigating” the issue. DNS stands for Domain Name System, which acts like the directory for Internet sites. It converts human-recognizable Internet domain names into numbers that can be read by the computers that run the Internet. In case the DNS system goes south, sites can become inaccessible, which may have happened in this case.
An attack on a DNS company can create havoc across internet, which may also stop websites from loading. That is mostly done through a DDoS attack, where the servers get so many requests that they are unable to respond anymore.
