AWS DNS Issues?

Anyone seeing name resolution issues in AWS? Some internal monitors started failing about an hour ago with name resolution issues. Quad9 is returning SERVFAIL for status.aws.amazon.com

Seeing this all across our EC2 fleet for anything on AWS. I think their service bulletin is underselling the severity because we are not using any third party providers. https://phd.aws.amazon.com/phd/home#/account/dashboard/open-...

AWS has just posted the following to their health dashboard:

> 7:21 PM PDT We are aware of intermediate DNS resolution issues for certain specific AWS names. This is due to an issue with third-party DNS provider outside AWS. DNS queries for domains hosted on Route 53 are operating without any issues at this time. We are actively working with the third-party DNS provider to resolve the issue as quickly as possible.

We also have issues with the AWS Route53 records resolving our CloudFront domain names. We get inconsistent results across devices and across the world

We’re seeing RDS dns hostname resolution errors as well. It’s been happening for an hour and a half now.

Multiple people have tweeted to @awssupport but they haven’t acknowledged the outage yet.

Same here. AWS is blaming some third party without naming names?

Yeah we're noticing issues too. Able to only intermittently load the status page and AWS console.

Seeing this in RDS endpoints too.

Also seeing this, we're on AWS lambda behind cloudflare. Tried switching cloudflare off, but still seeing the same issues.
