Earlier quoted context omitted.

I would imagine they don't use it for exactly that case. Imagine a case where most of AWS is having critical problems, you would want (at the very least) control of your DNS to attempt a partial recovery of service for some portion of your customers that have providers who respect DNS TTL's.

Netflix is 100% dependent on AWS for infrastructure. If AWS is having problems, there is nowhere to redirect to.

of course there is, they could redirect to a page explaining the problem instead of a generic error page...

Here are the sequence of emails we as a customer received:

1:44PM PST - The Neustar UltraDNS service is currently experiencing DDoS traffic in the U.S. East Region. The Security Operations Team is currently working on mitigating attack traffic and further updates will be provided as soon as possible.

3:07PM PST - The Neustar UltraDNS service is currently experiencing a major spike in traffic across several regions. The Security Operations Team is conducting routing changes and working to reroute traffic at this time. Customer will experience DNS timeouts and lack of resolution. Further updates will be sent as soon as possible.

4:50PM PST - At 4:18 EDT time, a service outage affected Neustar’s UltraDNS service. The impact was predominately on the East Coast of the U.S., however some impacts could be seen in other U.S regions. Neustar UltraDNS Service was restored at 6:34 EDT time. We are currently investigating the root cause of the outage and will provide an update as more information is available.

I am surprised that Netflix uses UltraDNS when they use AWS and they could be using Route53.

UltraDNS is more advanced / pro than route53.

Could you provide some details about how and why it's better?

Serious question here: Do people really spend $90/month for 2M DNS queries? https://www.neustar.biz/services/dns-services/managed-dns-pa...

And that's even without 'DNSSEC and IPv6 support', 'Regional Routing' and 'DNS Load Balancing (where available)', that's only available for 'UltraDNS Enterprise'... (I'm running my own (Power)DNS, after EveryDNS was bought by DYN and they didn't grandfathered old plans, charging per domain, which made it extremely pricey)
