Last Friday (21st October) morning began much like any other on the East coast of the United States. By mid-day, the Internet had begun to experience issues. By the evening, much of the public Internet was unreachable. Large sites such as Twitter, Amazon, Air B&B, Spotify, Reddit, The New York Times, PayPal, and the PlayStation Network and many more were for most of the US inaccessible. The sky that everyone had suspected would at some point fall down dramatically was definitely looking that little bit lower. A sustained and significant distributed denial of service attack against Dyn Inc. slowed much of the US Internet to a crawl, resulting in lack of access to all manner of resources, and much of the media began to freak out. For anyone involve (even tangentially) with IT security and network administration this turn of events was not much of a shock, but did provide an interesting indicator of the fragility of the infrastructure on which so many rely. According to reports that have emerged since, one of the major DNS service providers had been largely left inoperable owing to a botnet based around Mirai. In essence, toasters (well, IP cameras) had stopped the Internet working for much of America.
