Welcome
Headlines: DNS and BGP and DDoS Attacks—Oh, My! This week we cover a couple of recent service degradation incidents involving DNS providers
Under the Hood: Kemal Sanjta, ThousandEyes’ resident BGP expert, joins us to discuss the May 6th disruption to Neustar’s UltraDNS service, which lasted nearly four hours. We discuss the BGP routing changes we observed during the incident and what they can tell us about the cause of the disruption. We also cover a separate incident involving Quad 9, a public recursive resolver service, which the company says was caused by a DDoS attack on May 3rd.
