Getting good, consistent, well routed, fast and secure DNS Is harder than you'd think. Dyn typically sing speed as the main selling point for their DNS product, they do this through a large distribution of domain name servers geographically and anycast. Many hosts (like say, DigitalOcean) run their own DNS but use something like CloudFlare Virtual DNS on top. Personally I was surprised so many large sites trusted Dyn, Route 53 is a more robust product for production and scale. In the past, I've seen hosting providers switch to Dyn, give them load, cripple them, and have to scramble to revert away. I'm not at all surprised his happened, even given the uptick in botnet traffic globally.

Route 53 aint all that. We approached them about handling our customer's domains, and they said no way. They didn't have the capacity. Granted, this was 2 years ago, but Dyn has a much better reputation (still) than Route 53.
