Constant DNS Lookup Failures for all our monitors

Products

• CA App Synthetic Monitor

Issue/Introduction

Wednesday we updated our nameservers for our DNS zones due to an outage event we had.  

Since then we have been getting constant test failures from our monitors regarding DNS lookups.  We initially saw on Wednesday that our new nameserver IPs took time to propagate across the internet, and understood that could take 24-48 hours to fully rollout, but even w/ other external testing showing DNS was propagated. ASM is throwing these errors.

Is there anyway to either dump DNS cache on your side or check DNS for the domains in our tests manually to trace where the failure is?

Resolution

You may close this case.  We have confirmed DNS propagation throughout the internet is now working.
