Our infrastructure is heavily using Route53 and we are not seeing any outage. (~1000 domains)
Edit: from http://status.aws.amazon.com/
"5:19 AM PDT We are investigating reports of problems resolving some DNS records hosted on Route53 using the third party DNS resolvers 18.104.22.168 and 22.214.171.124 . DNS resolution using other third-party DNS resolvers or DNS resolution from within EC2 instances using the default EC2 resolvers are not affected at this time.
5:49 AM PDT We have identified the cause for an elevation in DNS resolution errors using third party DNS resolvers 126.96.36.199 / 188.8.131.52 and are working towards resolution. DNS resolution using other third-party DNS resolvers or DNS resolution from within EC2 instances using the default EC2 resolvers continues to work normally.
6:10 AM PDT Between 4:05 AM PDT and 5:56 AM PDT, some customers may have experienced elevated errors resolving DNS records hosted on Route 53 using DNS resolvers 184.108.40.206 / 220.127.116.11 . The issue has been resolved and the service is operating normally."

Azure Storage is a available in a ton of locations and all of them stopped working because Microsoft forgot to roll out their patch to renew the SSL certificate. So they knew about the issue but rolling out the patch was not done.
Another example was when they introduced HTTP2 for CDN endpoints and forgot to test the cipher list with popular browsers and broke compatibility with Firefox ESR.
