I’m joined by a couple special guests today to cover some recent incidents involving DNS providers.

This is The Internet Report, where we uncover what’s working and what’s breaking on the Internet—and why. I’m joined by two guests today to cover a couple of recent service degradation incidents involving DNS providers. In part one of the show, 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. In part two of the show, I’m joined by Michael Batchelder (AKA Binky) to discuss the two “Ds” of the Internet — DDoS attacks and the DNS. Watch this episode to hear about what we saw from ThousandEyes’ perspective.
