Infrastructure and DNS Redundancy is Key to Preventing Outages

According to Alexa, out of the 75K top ranking domains, 346 of them are managed by Dyn and experienced a complete outage yesterday due to their lack of DNS redundancy. While 346 out of 75K doesn’t sound like a lot, it is when you consider the amount of people that frequent the sites affected. Large websites such as Indeed, Chewy, Carvana, Fandom, Houzz, Sephora, and Credit Karma to name a few, took a considerable hit from this latest debacle.
