This is a pretty significant attack today and it affected a number of big name companies Twitter/Reddit etc, whoever is using DYN as their public DNS provider. And to a lesser extend, US-East-1 of Amazon Web Services is also affected My company was kind of affected as well including our third party monitoring devices http://gizmodo.com/this-is-probably-why-half-the-internet-shut-down-today-1788062835 The East coast area (where I am in) got hit the hardest apparently https://dailydot.relaymedia.com/amp/layer8/dyn-ddos-twitter-reddit-east-coast/ Any techies or sys admins here who would love to discuss this
