Google DNS intermittent ServFail for Disney subdomain

Fri Oct 20 03:41:46 UTC 2017

Hi Nanog,

I am principal network engineer for sister-studio to Disney Studios. They
have been struggling with DNS issues since Thursday 12th October.

By all accounts it appears as though *some* of the Google DNS resolvers
cannot reach the authoritative nameservers for "studio.disney.com".

This is causing ~20-30% of all DNS requests against Google Public DNS
8.8.8.8 / 8.8.4.4 to fail for requests in this subdomain.

The name servers reside in 153.7.233.0/24.

Might someone be able to *connect me* with someone at Google to assist my
poor colleagues who are banging their heads against a brick wall here.

Thank you,
David
