In a statement, Dyn said that this morning, October 21, Dyn received a global distributed denial of service (DDoS) attack on its DNS infrastructure on the east coast starting at around 7:10 a.m. ET (11:10 UTC).

DNS refers to Domain Name System services. DNS is an essential component of all Web sites, responsible for translating human-friendly Web site names like “example.com” into numeric, machine-readable Internet addresses.
